HELP! Problems w/ Climate Control
It seems my automatic climate control is going bad. I usually keep it off, but today tried hitting the auto button. That didn't work, but I can direct flow to the floor, dash, or bi-level. I can increase temp, but not decrease. I cannot change fan speed. After persistent button pressing, I can turn it off. I think the control unit is going bad, and I found it online at many retailers. I assume it is simply plug and play.
Anybody replace the control unit? How hard is it to install?
Thanks,

Remove the control head from the dash, unplug the connector on the rear and use a Q tip with electrical contact cleaner sprayed on it and wipe the pins on the head unit. Plug it back in and give it a try without reinstalling in case more work is necessary.

When I bought my 94, the climate control did funny things also. I found the vacuum supply(on the intake) was broken. then the temp control didn't want to work (computer control) I ordered a new control head on line (don'tremember from who) it was less than $200. I put it in (took about 15 minutes) everything works fine now. By the way, I took the old control head apart (not hard to do) and found the main circuit board was not plugged up good on the side that has the off and auto switches.

Now, I have not done this nor do I need to so don't rely on my old-fart brain's memory before tearing things apart. Hopefully someone will jump in here and correct any faulty info I may have given.

My 87 did that same thing. Worst of all it was set on 32*c when i found out the cool button wasnt working!! I ended up discontecting the battery to bring it back to default. Was simply the contacts inside the button being dirty on mine. My 94 has the standard controller. Its not hard to get it out, if you can get it apart and clean the contacts it should work again, but try the connections at the plug first!!
