Default '95 DeVille AC Blower Problem

Hello. I'm new to this forum and need some help.

Back in June, as the weather got hot, I noticed that my '95 DeVille's auto climate control would not run the blower on high when the car had been sitting in the sun for the day. I could set the temp. at 60F, and the fan on "High", but it would run real slow. After a few weeks, the blower started to run only sporadically. It would quit for a while, then come back. Then the blowerquit completely, but the compressor still ran and the dampers functioned. When the car was moving, I got a little bit of cold air through the registers; none when I stopped.

I took it to a mechanic who diagnosed it as a failure of the AC Programmer. So, I replaced the $700 AC Programmer (didn't pay that much, though) with a new one, and everything worked fine for about 2 weeks.

Now it's doing the same thing; blower on sometimes ( a small fraction of the time) and off most of the time. The programmer iscontrolling the path of the air (when moving, I get a bit of air out of the vents on "Auto" and out of the dash on "Defog") but the blower is not running (usually).

Can anyone help?

Thanks.

Hey there Bates: Have you thought of checking out the ambient sensor or the in-car sensor. Maybe the motor isn't getting the proper run signal from the sensors. You could also check out the motor grounds just to be sure you don't have a problem there.Take them apart and clean up the connection even if they appear o.k. Good luck with that.

Be sure you have power and ground at the blower motor when it is not working, if you do replaced the blower motor quite a common issue on these cars
