Ok, today I'm driving back from work and just enjoying how the car is performing now after I fixed a sensor and vacuum leak problem. Just then when I'm thinking what a great car this is, some demon posseses my heater. It goes BLANK and to full blast blower mode, full crank cold mode. None of the controls work, they all dead, can't turn it off, can't use AUTO nothing! Lucky for me it was blowing up against the windshield, otherwise I would have froze to death. I pulled over, turn the car on/off...still nothing. As soon as I restarted the car, it tortures me all over again. So I get home, pull the fuse to the heater and blower...plug it back in, turn the car on again...same ****. Now what TO DO?! Looks like its stuck in that mode, unless in the morning it will go back to normal..who knows? Any suggestions would be appreciated.
I'm not sure if this is correct, but it seems that the ATC when first turned on starts out on Defrost and works its way to whatever setting you have it on. Have you tried putting the ATC in debug mode and checking for a code or two?
Your wires can be loose or the unit itself is bad. My mom's 95 vision does this sometimes, just hit it with your fist a few times then it will work again untill you actually want to pull it out and check the wires and what not.-Simplicityfan
haha, no not yet. Anyways, I havent' had the time to yank it out to see if there are any bad grounds. I manage to fix the problem but just making sure its on AUTO mode all the time. Then it won't act up. Guess it wants to be in control all the time...sorta like a women.
mine has the same problem, I can't figure it out but I don't have to beat on mine real hard, I just tap it a few times on the bottum right hand corner and it works again. I also get the com failure (code 36 I think) when I do the debug mode check. I'll test the wires next and post again here if I find anything. The connections for the wire harness are right where I tap but on the other side of the ATC unit so that could be a hint.
What the heck?! Where the heck is the electronics made in these things, Haiti or somethin?
