Question about 2005 Pontiac Bonneville
Hvac blower won't turn on, i checked blower fan, changed fuses and resistor, no success in getting it turn on
Start by checking the blower resistor. It should be under the dash on the passenger side near the blower itself. You will need to remove the glove box to access it. It is a small plate that has only a few screws and a group of wires that go to a plug in the center. Unplug it and remove the screws. When you pull it out it should look like a series of small spring shaped coils. Most likely one or two of them will be burned up. Replace it in reverse order and your blower should start working again. If this is not the problem then test the fan motor itself. Hope this helps. Good luck.

The blower on my 2005 Bonny GXP quit at about 60,000 miles (I really like using High). The blower is under the passenger dash. Mine had a three wire connector. The center wire should have 12 volts. It doesn't take very long to pull the fan out. Mine was toasted. Aftermarket fan was about $130.
See this website for my instructions:

Check with a volt meter if your getting 12 V to the blower and if your not fallow to the switch if the switch is receiving 12 V and distributing 12 V you may have an open wire if your getting 12 V to the blower check if you have a good ground if you have both then you have a bad blower I hope this information is of use good luck

How did you check the blower motor? did you put 12 volts to it and it still did not turn on? if thats the case, the blower motor is bad. if you put 12 volts to the blower motor and it works, then it sounds like the BCM (body control module) is the culprit.
