Default Wierd temp. control (some help would be VERY NICE...)

Ok, my mom has a '95 SE

you can turn the temp control from cold to hot easily but usually when you turn it back to cold it keeps blowing hot air, anyone have any clue how to fix this?

let me know if you figure it out, I've got simiar problems with my '95 SSE. It'* either always hot or always cold. It pretty much decides on it'* own, so if it'* 90 degrees outside I'll eiter have nice cold air, or full blast heat. It'* just great.

Do you have electronic climate control?

Then check for binding cables or loose vacuum hoses. For auto controls, check for codes first. Read this for help: http://www.bonnevilleattitude.com/fo...opic.php?t=484

I tried the procedures listed for the 93-94 ATC. Evidently doesn't work for a 95. How would you go about getting trouble codes for a 95? Would they show up with a scan tool plugged under the dash?

Try one more thing... Try holding OFF and WARM simultaneously for 5 seconds when the climate control is on. If that doesn't work then it probably is different.

Nope that didn't work either. (to hold it for 5 seconds) If it did get skrewy buy taking the battery out, is there a way to calibrate it?

Then I guess you're looking at a Scanner then to fix, diagnose & calibrate this HVAC Control!
