Question about 2004 Pontiac Bonneville
I have a 2004 Bonneville SE. The cabin fan(s) worked great for 2 yrs, then started working irradically. Now, the blower fan doesn't work at all. If I turn the temp to heat and crack the window a little, warm air will circulate -- but the fan isn't moving ANY air. If I turn the AC on, select defrost and crack the window a little, cold air will circulate through the windshield vents. Otherwise, NO air moves in the car at all -- the fan doesn't come on at all. I have checked the four related fuses under the back seat. All appear to be good.
What else can I do? I'm not a mechanic, but I can do small repairs on my own -- *if* I know what needs to be replaced. THANKS!

it sound like its one of two things 1 it could be the function control knob on the dash is no good or that the vent/ def. door control motor is no good possibly seized up. the second thong that I would suspect is that the door itself is jammed in the on spot

Your fan seems to be drawing way too much current, common with fan motors of all kinds when they are going bad. It will still blow, but hot wires and blown fuses in the normal circuit indicate you have an excessive load in the circuit. Fan motors create this condition regularly, but are often ignored since they are "still blowing."
Here's a cheap, easy way to test my theory:
Try a new fuse, the proper amperage, but leave the blower motor unplugged at the blower itself. That will tell you in a few rides if the blower was the culprit. (Which it most likely is.) I bet your #20 fuse will stop blowing and no more smoking pink wires! Hope this helps. Remember, blower motors are cheap, traffic tickets and dash fires are not. The blower motor draw is the logical thing wrong with this picture. Good LUCK! TT

Check the blower motor which is behind the right side of the dash, in the lower right side of the HVAC Assembly, above foot area of the passenger floor. The other thing to test is the blower motor resistor which should be next to the blower motor.

for the fan blower motor it could be the resistor or the fan control speed control switch is bad.for no lights replace the DRL RELAY for the lights. for the heated seats check the fuses.
