DIY: No Heat? Repair the Heater Control
#126
No, you are not my father
I think you could do that maybe. The mechanic might even apriciate it. The hourly rate is going to kill you on this one. The mechanic is prob going to charge you at least three hours @ 70-80 per (210-240 min). 90% of this is done with pretty common tools so you could save yourself a bit of cash, even after buying a soldering iron and solder.

No worries. To each his own. Another option might be to get the whole unit and Just have the mechanic swap it in for you. Would be more expensive, but that doesn't seem to be an issue for you. One of the vendors here sells them, at least I think I remember seeing it on someones site. I'll see if I can find a link.

I just did this fix... A/C works good as new now! I must say, the solder job onthose three points from the factory was terrible! hardly any solder on it at all...

Hey I did this fix and now my heat works but after I put the radio back my instrument panel doesnt work??? The radio works but no lights on the panel.... I checked the fuses and they all looked good, I dont know which one runs the panel.. Any ideas??
#132
I figured out the problem, officially I am a dumb a**.. unofficially if you forget to plug back in the wires on the side of the radio before reinstalling it the instrument panel wont work..

I'm going to ask a dumb question for clarification - by instrument panel are you referring to the radio-A/C display or the gauges (tach, etc.)? The reason I ask is that if you don't get the small wiring harness on the left (driver's) side of the radio plugged back in correctly, it will mess up the radio-A/C display. I didn't get mine seated fully on reassembly and it caused an erratic display. If it wasn't plugged in at all, you wouldn't get any display. The backlighting would come on, but no text, numbers, etc.

Did this a couple of days ago on my daughters 06, and it works 100%. Only hard part was the disconnection of the wires. Otherwise great DIY. Saved me a pile of cash. Thanks again Wingnut.

The DIY worked PERFECTLY!
It was a royal P-I-T-A to unplug everything. One of the leads in particular is so short that was tough to disconnect and reconnect, but I managed after several tries.
Disassembly is super easy and soldering was no problem, though I strongly recommend no more than a 15amp soldering pen. Anything hotter and you risk burning a trace if you aren't careful.

I had this same problem. My car was stuck on the AC. It was fine until the fall started to really cool off. I opened the ac diagnostic menu, and my ac was stuck at 0. This is a great thread! Follow these steps exactly and you wont have any trouble fixing this problem!!! Thanks so much to the OP!!I finally have heat!
