...Help It's going to snow next week!!? The heat and air conditioning in my 2000 chevy impala are not working, the cruise and the thing on the roof of my car that tells me the outside temperature are also not working. a few weeks ago they all worked for one day then went back to not working. I have had all the fuses checked, changed one of the relays, changed the body control module, and have found that the blower motor is not getting power. Has this happened to anyone else? What did you do to fix it?
