Thanks for the help. My dad dropped his '04 Corvette this morning at 8:00 AM. By 9:15 AM I had already removed the center console, remove and opened the temperature control unit, soldered the resistors and put everything back together. Worked perfect! Much easier than I anticipated! I only needed a #10 mm, #7 mm, #15 torque, 3/16 nut driver & solder gun to do the entire process. Gotta love TH-cam!
Many Thanks! Got an 02 Z06 and display was fading fast and could only see it at night, and not very good. Took the module out in 5-6 minutes. Showed your video to a local electronics shop and they soldered the resisters and told me that all 8 were literally about to fall out. Now the display is back to factory. 😆😆😆 👍👍👍
That was extremely informative...Mine has been so dim so long & I couldn't find anyone who could help me. All I could get out of anyone was "well that will run you about $400!" And then they would just Laugh in my face! I really appreciate the time & trouble you have gone too.....Thanks a BUNCH!
Just performed this repair, worked great. From nothing to clear display. Took me about an hour and a half including figuring out how to get the console apart. Thanks for teh great instructions.
Thanks for the tip, I read the procedure on a forum but didn't think that was the fix after visual inspection. Then I watched your video, worked like a charm.
Hello from Dan. Thank you for posting this. I performed this operation today. Works as described !. I can now see my HVAC display ! I could always see it, but often it was very dim. When I resoldered the resistors, 2 fell off when I applied heat to one side. That tell me the other side was actually broken lose on the other side. 1999 C5. I'm also replacing my broken shift pointer with a metal one. Thanks. Dan kb7uxe
This does work. I did my 2003 a few years ago. Was dim when I purchased the car used in 2008. Not a difficult job, but a little time consuming. I would only suggest that if you do this to your car that you do a little better job with the soldering iron. The point of doing the job yourself is not only to save money, but to insure that the job is done properly.
Dude, thank you so much for making the video. I followed your advice and resoldered the bank of eight resistors. Reinstalled the controller and got a nice bright display once again. Appreciate the effort brother, juts saved me about $500+
The tips to fix the heater control module display worked 100% for me. Visual inspection didn't reveal any problems, but resoldering the 8 little surface mount resistors restored mine to like new condition. However, as he mentions in the video, it is good if you have some electronics experience. You need a tiny soldering pencil and experience with surface mount components. Otherwise it is probably best to just take the control unit out and get it repaired somewhere.
What I would do is I would replace the resistors with through hole parts, mounting them so that there will be less stress on the solder. Although, only if there is enough space to do so. The resistors would be glued somewhere appropriate, and then wired to the pads on the board. My suspicion is that the resistors run hot, so they create a lot of thermal expansion/contraction stress on the solder. This has been a problem in many other electronic items. Also a problem is lead free solder. There are some lead free solders which are good, but some are brittle and will crack easily.
I see that you have more solder on those eight pieces you mentioned touching the tip of the sodder pen did you also use more solder by the way thanks for sharing save me a lot of money
Part was refurbished then I installed but it still did not work. I checked fuses and relay switches, all were okay. Do you know what else it could be? Please help, thanks!
My only suggestion would be to test it BEFORE you put the dash back together. I had to solder twice (because I'm not good with a soldering iron) so I'm glad I was wise enough to test before putting the dash back together. Once again, this video is awesome and every time I start my Corvette, I think of this video and smile because I saved $500.00.
Thanks for the information I'll be working on it soon I have an 01 ZO6 and is throwing all kind of codes but what's the heater unit has been giving me trouble for last few years and now it just finally quit
Great video for climate control display repair but you should of replaced the back lighting bulbs while you had it apart and your solder would of flowed a lot better with the use of a little extra flux , just trying to help !
I used an old small soldering gun and ground the tip to a small point. It takes very little solder to fix it and maybe none at all, just heating the circuit should melt the old solder back in place. Yet, I used rosin core solder and it worked perfectly.
i am currently doing mine. however the chip board or whatever you call it that you had to sodder on is different that yours in the video. mine is a 98 convertible. is the number on the things you sodered 241?
TNW2 - clean all grounds and put heater control curcuit board under a microscope to see if any bad / cracked solder joints - Good luck on Nov 3 - Cheers from Canada!
Just want to point out some dude on ebay will fix this and update all the bulbs in the heater control module for only $109... but you will still need to remove the head unit yourself. Still, a pretty good deal.
Thanks for this video, awesome info. Can you make a video on fixing the fuel gage issue on c5 corvettes? I've got a 2000 that doesn't read the right level, can change every time I start the car. It won't move as I drive the car and burn the gas off.
I will if one comes in needing BUT you should check your car for recalls to see if there is a free repair for the gas tank(they crack on some C5s) - if there is then have them stick in a new sending unit
Easy as anything - use a torx screwdriver - remove two screws on top and two more that or located at the bottom on each side - then wiggle lift straight up - that"s all there is to it - let me know how you make out - cheers Michael
My climate control works great, the button trim lights do not go out when car is shut off. This runs my battery completely dead everyday. They also will not dim with the dash light dimmer. All the other button lights go out with the timer as supposed to. Any thoughts?
I have no power to the climate Control module it isn’t working. Because The number 16 wire, the lead power wire, is not getting any power and I have no a/c or heat. What do you think the problem is. Thanks for your help and god bless.
Jay - Check fuses 18 and 27 - The HVAC control module doesn't have a #16 wire according to my GM corvette manual - so sould you be more specific as to color and pin location?
My mechanic took mine apart and cleaned it. He thought he fixed it. My thing is. It powers on and everything works great. Then it powers off. And turns back on when it wants to. Could be a minute or hours. Same with when it has power stays on minutes or hours. I washed my vette today. The unit had power for 45 minutes while the car was on. Then I turned the car off went inside the house came back out and started it then bam no power in unit. Turned it off. Started it back up to put in garage the unit had power. Turned car off in garage then back on. Boom no power to unit. The display is bright nothing wrong with display light. Just main power to it. Very frustrating
Donny - you have the manual control that has 3 rotary knobs that came on some vettes - others have an automatic system such as the one in this video - Cheers from Canada!
It worked to bring my 01 C5 Convertible climate control system back to life, but I am unfortunately I am going to need work done on the system as I have it on 65 degrees F and it is blowing hot air.
@@carquestions You're probably right. I'm going to have my shop that services my other vehicles diagnose it. Hopefully it won't cost me an arm and a leg. If it does I'll put it off till the spring since we're rolling into fall in the Midwest. I just need to make sure the heat's working so that I can drive it this winter when there's no snow on the roads.
@@carquestions Thankfully I have a buddy that's an independent mechanic who will likely charge me half of whatever the big shop tells me the AC repair is going to cost.
I did this exact repair about 5 years ago on my 2003 C5. The display has been working flawlessly ever since.
Keep on Fixin Greg - Cheers from Canada!

so you just reheat the solder and get it to reflow?

I would suggest using SN64 silver solider and also a ground strap on one of your arms. The microprocessor is very sensitive to static electricity
Thanks for the tips,all went well as you described!

Why not reflow the resistor you had flux on your bench then it would not look messy as you call it?
i am currently doing mine. however the chip board or whatever you call it that you had to sodder on is different that yours in the video. mine is a 98 convertible. is the number on the things you sodered 241?
If the resistors look the same just resolder anyway and give it a try
On my 1997 corvette the heater ac control turns on and off by itself. Any ideas what's wrong?

I wonder if that could affect air conditioner window air conditioners fully controlled are charged in this unit doesn't seem to be activating
Not likely
Great video!!! Thank you for sharing.
anytime
didn’t work for me, any tips ?
did you look at the circuit board under a microscope? - 95% sure it is a soldering problem
Yup, Easy DIY fix.. take back off of the unit, re-solder the small squares in rows! It works!
Thanks for the comment Jared - Cheers from Canada!
thank you for the video mine stopped working im gonna give it a try lol
No problem anytime
