I have the same problem I think... I have a Malibu 2002 LS and the air only works on 4 and 5. I have checked and replaced all of the fuses related to the HVAC. My question is this; can I fix this problem using the same instructions for the earlier models?
Thanks in advance for any help anyone can give!
Oh yeah, when I replaced the fuse for the IPC/HVAC BATT in the driver's side instrument panel, the air conditioning worked perfect for about 4 seconds... then would only work on 4 and 5 again.
