Great video! Love that you show your thought process for finding and troubleshooting the component and explain each step logically instead of just saying what to do without context.
Great tips I appreciate it 😎👍 I have a simpler issue. I had the fan working sometimes I hit anbunp and it works sometimes but not anymore I felt the fan blades it moves freely and sometimes I feel it trying to turn on I’m curious
I have an issue where my interior fans come on whenever they want to but I can’t turn them off or change the fan speed, I have replaced the blower motor resistor which fixed the issue for all of 20mins… what would you suggest
A relay can be damaged by pulling it out although it may not be noticeable. If one of those prongs gets pulled out even a millimeter it may not connect properly when reinstalled. This happened to me so I pressed each prong and felt one move back in place, then it worked. Now I always press each prong to be sure it is firmly seated in the relay before reinstalling.
Hello sir today I hade unusual problem I took of me wire harnest I was curiuse to see how the 2pin warning lights on buzzer relay is conected and I traced that positive wire to light switch and the other pin from the relay goes to the blower motor resistor so thats where me confusion comes from ??? What has the buzzer to do with blower motor ???
Seriously? You uploaded at the perfect time because my Acura TL '04 is having this problem at the moment. When its cold, my fan only blows when I've been driving for 10 minutes or more, but sometimes it doesn't blow at all. What is this? I never have this problem when the weather is warm Thanks for the upload 🤙🤙
If you have a decent scan tool, you'll be able to see the fault code. In your case you want to look for a 'B' code; such as B1202. If you can obtain that code I can help you further. If you don't have a scan tool, your local auto part store may check for free. I use this scan tool for the Acura: amzn.to/31lXxFl
🙂 I bought the Polish made multimeter. It has 2 wires, one has red & black stripes, the other has black and red stripes. (Thats the type of self-deprecating Pollock joke my Polish stepfather would've told. RIP). 👉 Seriously though, I'm trying to help a friend, who has a 2001 Lincoln Town Car as a backup car. It's heater/AC blower does not blow any air, at any setting. I've spent over 2 hours online trying to figure out the potential problems before I head over there. Two auto parts stores gave me prices for the heater fan relay, but the actual Ford dealership parts guy told me they don't even have a relay listed for the 2001 Town Car. He said it's not that they've stopped carrying it(which _IS_ the case with the blower fan motor), it's that this car 'may not' have a relay to begin with. Also, I've gotten contradictory info about the blower motor regulator/resistor. At least 1-2 people online said that, based on the symptoms of "blower fan not running at any setting", the regulator could be the problem. But more people have said that if the regulator/resistor was bad, the motor would still likely work on high, but not on low. However that's not the case here. I've also been told the physical climate controller switch on the dashboard could be the problem, BUT it's much less likely.
Thanks a lot. Can you go a step further, 1980 280zx. Blower does not run via control reostat. 12 volts direct to motor it runs. Relay checks ok, thanks to you. Now there is a blower control amplifier also but no clue how to test that or what it does. Also would love a lesson on reading wiring diagrams. Thanks again. Bob
Great! Thank you so much, and I have a question for you if the relay is malfunctioning can this cause intermitting function of the blower fan or is it like a fuse that when the connection is broken it doesn't work at all? I ask this because there are times when the car is running for a while and the blower will kick in or if I turn the car off and restart it with the fan in the on mode it will run for a very short time and then cut out again. Sure would appreciate your assistance with this today it's -30+ and the heat would be good :))
@@jeeplibertyinstall10 No because the relay being stuck on means that the circuit is closed so power is being supplied to the fan. If the fan turns off when you shut off the ignition the relay is turning off. It sounds like the actual switch in the cabin is faulty so that it is not turning the relay off. Turning off the ignition cuts off power to the switch. Sounds like it is the switch that is stuck in the on position, not the relay.
@@rogerg4916 true that was the next replacement just a used one. Would you believe I got a new resistor and blower motor just to put all the old ones back in and resolve the problem haha
You're one of the very few people who knows just how to explain things.
Great video!

Thank you. You are a very good teacher. ✨👍💖 This video is very simplified and it helped a lot.

❤ your video. Very helpful video. It helped me to pin point my blower problem
Hi, I heard you say look for the Wifi hotspot?

This happened to me so I pressed each prong and felt one move back in place, then it worked. Now I always press each prong to be sure it is firmly seated in the relay before reinstalling.
Another great well informed video!
Thanks a lot mate ! That's a very helpful tutorial !
Happy to help.

What has the buzzer to do with blower motor ???
Do you need to disconnect the battery before replacing the relay?

@CarsNToys I would also love an answer to this question as I am having the same issue!!!
@@amandarogge5775did you ever find an answer? My relay keeps randomly stopping and starting as well
@eg-sx1qx unfortunately no, didn't hear back at all. Hoping they answer soon as I can't seem to find a solution
What if my blower motor keeps turning on with keys out of the ignition? I have a 99 Expedition.
Where can I get the power pack your using.
What does it mean when it only goes on when you slam the passenger door .....
My blower fan is stuck on my 99 Rav4. Any suggestions on what it might be?
A bad relay can also cause the fan not to turn off even with the key out. In this case the relay is stuck in the on position.
I always learn alot thanks for the video 👍
3019 Kia Sorento relay blower motor keeps blowing
Why not just swap out the rear defrost relay and test the blower? They’re the same, aren’t they?
Thanks

Could it be stuck if the blower motor won't shut off unless the ignition is off

What about output voltage?'
2005 Chrysler 300 blower motor fan
why does a fan need continuity on 2 separate terminals lol
