location of front heater blower
I'd check under the glove box. I replaced a relay that controlled the blower and it was up under the glove box. Get yourself a Haynes manual for $20 and it'll come with PICs/description.
On my 03 GMC envoy xl. The heater won't shut off when i turn the car off and it killed two new batteries so far.
So what ended up being your problem? I am having the same issue with me envoy at the present moment.
