Maybe the fan blower motor. Check for wore brushes on that first.

sounds like a bad ground. with the blower on, measure the voltage between ground on the battery and ground on the blower. it should be less than 0.1v. if more, repair the ground. if ok, it may be corrosion at the fusebox or the HVAC module its self

SOURCE: A/C Heater blower fan does not cycle through all speeds

Yes it is the blower Motors Resistor board. It is up behind the blower motor, just under the glove box. You have to remove the black KICK panel with its two "Push Pins" that will break too. There are 3 screws holding that resistor board in, the back two are a bear to get to. Good luck.

SOURCE: Blower motor vent selection switch not working

the hvac selector switch in the dash may be the problem.You need to remove the switch and look at the connector on the back of switch,see if there are any burnt wires at the connector or switch.It's all electronic and the switches have been known to burn out on this and other model.

Where is the fan switch on 2002 Buick rendezvous located at??


Do you have automatic temperature control? If so there is no fan switch (mechanical that is) it is done through a electronic speed control circuit. The dealer can scan the systems control module and it will generate fault codes for any issues it detects in the Heating/Ac system. You may just have a defective blower motor as well but you gave very little information about exactly what is occurring in the fan, no fan only one speed etc. Please add additional info for more precise help. Thanks have a good day.

Heater blower stopped working?


Hello,
You may want to try your fan on all speeds. If it will work on high, you have a bad resistor for the fan motor. ( high speed doesn't go through the resistor ).
If it doesn't work on any speed, I would check the following;
1. Make sure the fuse isn't blown for the fan blower motor.
2. Check, or have checked the wires between the fan control switch and the fan blower motor.
3. Have the fan control switch checked.
4. Have the fan blower motor checked.

I hope this helps you.

Yes check resistor, motor, then switch. but as you say by banging on dash made it run. then I would look at a bad fan resistor first. or a loose wire in dash.
