Thread: 02 Grand Prix Dual Climate control problem

i know this is a old tread but i only saw a few people say it was fixed the cold air one side hot the other, i had the same problem, and if you think back i bet u had your battery removed for some reason, just prior to this problem happening, if u put the battery back on poss first and neg second the computers that work the actuator door freak out, so i would first try to unhook the poss side of battery, leave it off for 15 minutes,leave the neg side on, after 15 minutes put the poss cable back on, it should work just fine, if not try again, as i did have to pull my battery again after i fixed it and it went out of whack again and it took 3 try's to get it back to normal, hope this fixes someones problem,,worked for me 2 times already.

The battery thing, thats a good one. I heard that as well and tried it twice. It didnt work. i guess maybe i should have tried more times.
i still have the old control. If it acts up again, i will try the battery with both controls.

last time i left it off for 4 hours, and it was still messed up, then 30 minutes, then 15 minutes, i also make sure nothing is on, no doors open key is off, when i reinstalled the battery, and then turn the key forward, but not to crank, just run and that seems to be when all the actuators adjust them selfs. when u re hook the batt the dual climate control should just be on auto already when u turn the key as well, good luck, its something to try during commercials, thats how i found the time.
