Replying to: yakkymom (Jan 20, 2008 12:40 pm) You might check the passenger compartment air filter that is right above the blower motor. My heater quit blowing altogether and I checked the air filter and it was wet and stopped up. I changed it and it works better than ever. All vehicles from the 90's up have an air filter coming from the blower.

Replying to: rgh1016 (Feb 24, 2008 10:49 am) I have had the same problem auto care center said ac/heater control unit was bad they were wrong. If you unhook your blend motor from the door unit but leave wired turn your car on and turn your temp. down you should see the motor move if it is not lined up with the marker line on the motor take apart blend motor case and align gear with mark you may have to do this two or three times to get it right there is some type of travel sensor in the unit . once you are satisfied with this with your hand turn the actuator for the door to insure in right position (cold air coming out) the motor should slide back on with ease if everything is in the right spot . Let me know if this works for you

#178 of 192 Climate Control Problem - 97 GTP by jakedave Apr 24, 2008 (6:50 am)
I have a problem with my climate control. The external thermometer reads the wrong temperature, which makes the climate control not work either. For instance, yesterday the actual temp was around 70 degrees, and my thermometer read -6, so it will not turn the a/c on or anything, and it happens once in a while the opposite way too (like it will be zero outside and the temp will read like 90, so it wont heat properly). I replaced the ambient air temp sensor and it did nothing for the problem..Does anyone know what the problem would be? Thanks    Another small problem I have is that my automatic lights do not work all the time.. They wont work for like a month or so, then all of a sudden, one day they will work, and will continue to work for a few weeks or months, then out of the blue they will stop working agian...i tried replacing the headlight switch assembly just because it was cheap and i figured i didnt have anything to lose, but it didnt solve anything...anyone know what that one would be?

#181 of 192 2000 GTP blower fan by slemiska Jul 17, 2008 (9:53 am)
My heater/ac fan stopped blowing. when the AC is on I get cold air just no blower. All the controls to switch where the air is coming out and what mode it's in seem to work. Where do I begin to figure this out.
