Question about 2002 Buick Rendezvous

1 Answer

Low speeds on Blower Motor do not work.

2002 Buick Rendezvous blower motor will not work on speeds 1, 2 and 3, but will work on 4 and 5. I think it is the blower motor resistors, but I do not know where it is located and then how to get to it.

This is caused by a burnt out blower motor speed control resistor module.

    The resistor block is located right next to the blower motor. Right side of instrument panel, under the dash.

Blower fan not working at all 2004 Buick rendezvous


Which system ?
HVAC Systems - Manual HVAC Systems - Automatic
If automatic it's probably the blower motor control processor .
Blower Motor Control Processor The blower motor control processor is an interface between the HVAC control module and the blower motor. The blower motor speed control, Blower motor speed signal, battery positive voltage and ground circuits enable the control processor to operate. The HVAC control module sends the commanded blower motor speed to the control processor through a 0 to 12-volt linear ramped blower motor speed control circuit. As the blower motor speed control voltage increases, the blower motor speed increases. The control processor sends the actual blower speed to the control module through a 0 to 12-volt blower motor speed signal circuit. The processor supplies 12volts to the blower motor through the blower motor voltage supply circuit. The control processor uses the blower motor ground as a low side control to adjust the blower motor speed.

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.
