How to fix your fogged up Tesla tail lights

- This is the most common problem Tesla mobile service technicians deal with currently.
Even if you qualify for a replacement light assembly under warranty, think about what happens to the original part. It's thrown in a bin and sent to be recycled. What a waste! These light units can be repaired cheaply and easily and we show you how.

Here's a great video explaining how Gore vents work in this application: • Part3: Condensation
Important note! At 11:10 I show the foam gasket being replaced AFTER I re-installed the unit. I should have put it back on BEFORE I put the unit back onto the lid, as its purpose is to seal the area around the connector to the boot lid and prevent water ingress there.

Manufacturing fault. Replace under warranty. Subscribed as a quality piece thanks,
Yes, it's a fault with Tesla's supplier and I've had a few comments which say just get it replaced under warranty so I wanted to pin this comment and remind everyone why I made the video.
1. Even once replaced under warranty the new unit can suffer from the same fault. This is still happening as of January 2021.
2. When the light unit is replaced by Tesla, it isn't repaired, it's thrown in a bin. The contents of that bin hopefully will be sent to a recycling plant, but I don't know for sure. Even if it is, that's thousands of light units being recycled needlessly.
3. There are older cars out of warranty suffering from this and owners might want to avoid an expensive repair now or in the future.
4. The more we publicise this issue, the more likely Tesla will fix it once and for all. Tweet it to Elon, spread it on forums and link it on FB groups.
5. Some of us actually enjoy doing stuff to our cars rather than hoping someone else will fix every problem. As you may have realised from watching this video, my first car wasn't new and didn't come with a warranty. I learnt a lot about cars from working on my Cortina and it means I can still fix simple car problems without visiting a service centre or paying someone to do it. It's becoming a lost art, but I think it's still worth considering even if you are lucky enough to own a new Tesla.
Thanks for all the positive comments and supporting the channel!

Totally with you but if 499 550 cars go back to get fix done Tesla will sort the problem out. Boats don’t have leaky welds🖖🏻 cheers.
@@Ifyoudonttakeitucantfakeit Lol, you have more faith in Tesla than I do.
You have more faith in your diy skills than I have in mine! End of day the cars do fab I don’t mind some condensation. At nearly 4 years old I will get them changed. Now, phantom braking is a priority to fix, they can’t sort that out which seems odd. I forget all my Tesla hate when I nudge the pedal👍
@@Ifyoudonttakeitucantfakeit if you push pedal inside, it will go and when you dont push it will go red after it goes on the ramp. you should always check the pedal if the ramp is going red or green when you drive. fog is inside only when the door is closed and when you drive on the green
Nice video. I went to Tesla SC to ask them to check the tail light as it has condensation. They refused saying that it's mentioned in the owner's manual and it's normal. This is the excerpt from the owner's manual:
"Condensation in Head or Tail Lights
Due to weather changes, humidity levels, or recent exposure to water (such as a car wash), condensation may occasionally accumulate in your vehicle’s head or tail lights. This is normal- as the weather gets warmer and humidity decreases, condensation often disappears on its own. If you notice water buildup within the exterior lenses, or if the condensation affects the visibility of the exterior lights, contact Tesla Service."
It's anti-consumer. They want to get rid of their responsibilities.
Bravo. Excellent video script, excellent shoot, editing, lighting, sound.
Thankyou!
@@TeslaGurus has the issue ever recurred on this repaired unit? I did a cursory scroll through comments and read video notes but didn't see any follow up.
@@Muonium1No more misting since I repaired them. Permanent fix!
That's 100% correct. The seal is the problem. The caseworkers like a balloon, if the air gets hot inside the case will expand. Once the air inside cools down it will suck wed cold air in the case. And yes the GORTEX pat is there to compensate for the airflow. GORETEX can let air in and out but will prevent moisture get inside. So if the seal haves a bad spot, moisture will find its way into the case. A long time ago I have designed waterproof polyester TL light cases for home use, we had the same problem if the seal was bad. GOOD JOB MAN ! And thank for saying it is not only TESLA ;-)
Thanks for making this fantastic guide! I was able to solve the condensation issue myself by following your clear steps.
This video is really helpful even if you don't have a Tesla as it shows you things about headlight construction and how to identify and correctly fix the problem.
In older cars you would have a ventilation valve, but my car didn't seem to have one , after watching this video I noticed that similar to the Tesla it has a white ventilation patch.
Well done! Nice job on correcting the gasket mistake as well! Tube was a great idea. One tweak might've been to use tube and gentle vacuum to draw sealant into voids. All in all, an amazingly patient, wise and thorough video; 5/5 stars!
Thanks John, identified the problem, and come up with a cure!
Wow! This was eye opening! 😅 Thank you!
This is amazing. 1st class content.
Thanks John. Excellent stuff. This will be so helpful to so many of us. I've subscribed and look forward to future ones. Very professional 👍
This video deserves 100,000 views
I agree!
Fantastic all round. Thank you!
Very interesting. Thanks for the time you invested in this, I am sure it'll prove useful to many people in the future.
Outstanding video. Can’t wait to see what else you have out there.
Great vid, nice to see a UK Tesla tech vid.
What an excellent explanation and film. Thanks
Extremely clear and conclusive instructions
Wow the detail in this video is amazing you guys are awesome well done cheers!
What a godsend!!! Stopped at the charge point at the Tesla Manchester service centre and asked a technician about condensation in the B pillar and tail units and was told that was due to being LED and that's it! Brilliant to know that one can actually fix it. Great video and feeling confident about tackling it myself following your instructions.
Brilliant, video. Love not having to waste a Ranger visit or adding to a landfill.
Couldn't agree more!
Thanks for a thorough and informative video on how this happens and how to fix it! As well as showing how this happens to the B pillar cameras, too! Both have happened to my 2018 Model 3 and now I understand it completely. Good work, guys!
Nice spirit of repairing it yourself, love it 😁
A hair dryer should dry it out pretty quickly once you have the Gore patch off. Not a heat gun, just a regular hair dryer.
On LOW! That’s an important detail haha
Yeah, I was really surprised he didn't suggest this. Light would be dry before the oven is even done pre-heating.....
@@beyerch It is different approach. You put in oven if you want all moisture out (like this lamp), hair dryer can work on flat, easy to reach surfaces. I had experience in the past, that oven works wonders.
Very well explained. We have this problem. Many thanks. Keep up the good work.
Excellent video and workmanship!
Thanks, great advice for a common and annoying problem!
Incredibly simple and informative. Well done! Thank you
Very nice explanation.
Thank you very much! Time to sort-out the light on my Model3.
Excellent video. Many thanks for shooting this episode. I don't have any fogging in the lights of my September 2019 Model 3, but if I do ... you've produced an first-rate demonstration how to fix it. I've subscribed!
John, excellent video, thanks for the added encouragement beyond the DIY, to save resources and energy by fixing your own lights.
One of the best instructional videos I have ever seen. Good job!
Such a well made guide. thank you
Excellent video. 👍
Genius method and awesome procedure….
Awesome timing. This week I've seen one of my tail lights go just this way. I can see what the weekend will have me doing!
Thanks for this guide video. Very useful why it happens.
Wow amazing guide, will try to fix mine.
Excellent explanation - very thorough, and very helpful. Thank you!
Excellent video. So useful. I don't have this problem at the moment but if it happens later I'll know what to do. Many thanks.
Excellent informative video, beautifully produced. Looking forward to more from you. Thank you.
Much appreciated!
Great video. Many thanks!
Excellent presentation. Very reassuring for anyone looking to tackle this issue on their own vehicle. Thankfully mine have only misted on a few occasions and the Gore breather has been sufficient to clear them. However, it's great to know that there's a ready DIY solution if needed.
Beautifully explained, thank you
Well done. Thanks for posting 👍
Great professional video thanks!
Great DIY video with good problem solving techniques.
Appreciate the workmanlike approach to the video. Cheers.
Glad you liked it
Big respect for for this video. Well done!
Glad you enjoyed it!
great video/explanation! Thank you
What a fantastic video! Thank you so much for showing us how to fix this problem once and for all! I also hate to see resources being wasted and I can’t see Tesla taking the time to glue all of these and to replace the goretex patches.
Great information! Thank you!
Excellent video, thank you!
this is a really nice video. very helpful as out of warranty.
Great video. Keep up the good work.
Great video! Thanks!
Excellent video!
Thanks for this one. Even though I don't have this issue I like the approach to repair and imrpove
Fantastic video! Very informative.
Great video, thank you! Well done and very helpful.
Thanks! Really informative. Cheers.
Super Thank you - I look forward to repairing my model 3 🧐
This was great. Thank you.
Just had mine replaced Yesterday! Now i see your month old video🙃
thanks for the info
Just found this channel. Some of the best quality content for Tesla owners
Glad you enjoy it!
Excellent video
Thank you soo much for this very informative video!! I just baught a Tesla like a month ago and it’s been raining quit a lot here and I noticed my rear light started to get foggy so this video is definitely gonna show me how to fix it with out having to replace it thank you 😀👍
Great video! I’ve had my rear passenger taillight replaced now 3 times and wondered if there was a way to fix these. Will be trying this method if it happens again!
I used Permatex and it is amazing too. Thanks for the idea.
Cool little trick to find the leaks. Thanks. The fog lights on the front bumper also have some water condensation after a rain, but then they get cleared a day later.
Informative , thanks .
Great presentation! thanks so much
Thankyou , I have ordered some liquid sealer , great video
Great explanation
Brilliant video. Thank you.
Brand new Model Y, same problem on week-1. Thanks for sharing the video. Good instruction in case Tesla service won't do anything to it.
Excellent explanations. Tks
Glad I found this, the same light on my is misty, wish me luck.
Thank you... got my left and right replaced several times. Hopefully there won’t be any next time. If not, I will follow your instructions.
Great video and an easy fix.
Thank you ... just purchased my 6 month old Tesla 3 P yesterday and all four already now steamed up ... will do as your video stats ... 😀👍
Great video 👍
Great video for those living too far from Tesla SC and beyond Ranger reach.
Great vid, straight forward and seems easy to follow if I ever need to.
In terms of future videos... any way to do one covering hunting down rattles and their fixes? Maybe a compilation video with general guidance? It feels weird booking a service appointment for a rattle that I'm sure I should be able to fix.. if only I could find it's source...
Very helpful video thanks
Very nice job, buddy!
Great job in diagnosing this issue. It's the first real explanation I have seen. I bought a used 2022 Model 3 and the taillight had condensation in it. The dealer I bought it from agreed to install a new taillight and I have not had any problems with condensation forming in it. So, it is possible that Tesla has corrected this manufacturing defect. It appears that is the case. It only makes sense because it would cost Tesla a huge amount of money to repair these under warranty.
Again, you did a superb job in diagnosing and fixing this issue. You did an amazing job!
Well done!👍
Brilliant! Thank you!
Thanks for this.
Thank you mate we bought a set of extreme taillights for the model 3 from Hannshow and as soon as we would wash the car the lights would fog up so thank you very much for showing us how to fix the tail lights never seen 1 ounce of fog since. Which we fixed 6 months ago after watching your video.
That's what I was assuming the issue to be but wasn't sure how to fix. Thanks! I really like the idea of fixing it myself rather than having to waste personal time going to a service center and knowing the old highlight would be thrown away/recycled when it could easily be fixed.
Tesla is a dream for DIY. Other manufacturers fix it for you
Well done, friend! Thank you!
Very nicely done! Over 3-years now of ownership I've had Tesla replace 3 taillights when, if I had seen your video, I could have saved the wasted plastic and fixed the lights myself. Next time! Thank you!
Great video. Thanks.
Excellent. Thanks.
Thanks! Very useful!
....great vid with an excellent relaxed presentation style. I have a late 2020 M3 that had a fog lamp replaced due to water ingress. I agree with repairing rather than dumping and always enjoy the challenge. It's just a shame that a £50k car needs this sort of remedial work.
