    2002 Seville HVAC blower help

    2002 sts approx. 80k miles. Blower motor runs when it wants to. Doesn't matter if in auto mode or manual mode. Compressor kicks in like it should but only on occasion does the blower fan come on. Rear fan works manually like should. All the door actuators seem to be directing air properly...just no volume. Checked codes and came up with several u1255 Class 2 communications fault....u1301 class 2 short to battery....1340 air mix door movement fault. Several others that I'll deal with in another thread. When blower does come on...everything seems peachy. then next key cycle and nothing...???? Driving my mother in law nuts which in turn she drives me nuts. All help appreciated. Darrell

    Replace the blower or if you are good enough, remove it and open it up. You might find a loose or burnt wire or brushes.

    Thank you for the welcome.... I would have thought if blower problem that it would not be so quiet etc. when it does choose to run. You can turn it to all speeds and on and off ...works great. Then next time you start car nothing ...no blower what so ever. I thought some kind of control or signal issue.???

    Have you been through the owner's manual to practice setting the various personalization functions - including the HVAC system ? (Far out guess)

    A loose ground is another possibility, but I'd bet on the blower. Do a search and you'll find it is somewhat common.
