i have an 05 hummer h2, that has recently having heater blower problems.
when using the windshield wipers, it either cuts out the blower motor for the heat. sometimes not being able to get it back to blowing the hot air again.
could this be tied into the wide problem with the wiper motors? it seems to act up most when wet? also the compass on the mirror will reset at the same time as the blower motor cutting out? electrical?
i look forward to your opinion,
jon

this can be the bcm module needing reprogramming, a bad ground which you need to clean battery to engine and battery to body and body to engine grounds. It may also be a bad module.
