Replace the thirmister by the electric motor, it's held on by two screws and has 5 wires to connect to it, it controls the heater speeds and sometimes burns out and will not allow blower to work, when you pull it out you will see wires wound like on a clothes pin if any are burnt then replace it, costs about $10.00

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.

1996 buick riviera heater blower won't run. I jumped the motor and it runs. Turn on the switch and it won't run


you have a piece of solder broken off the controller of your hvac unit, causing power not to get to the blower motor it self. take test light and see if you have power at the blower motor. check and see if you have continuty or brake between the power wire at the blower motor and at the hvac control unit. if wires are good then the problem will lie in the hvac control unit. check and see if the blower is working at all speeds, if it works on some speeds thens the blower motor resistor.

Got a 207 chevy tahoe ltz--rear air works ---front air does not work. any suggestions?


"2007 chevy tahoe ltz--rear air works ---front air does not work." Hi! I guess you are referring to the front hvac blower not blowing air at any speed and not coming out at any vents at any mode position. If this is the case, you can start with the fuses at the underhood fuseblock. Check out the three hvac labeled fuses. If found okay, and the hvac controller on your dashboard seemed to be working normally, you better check out your front hvac blower motor underneath the right IP section. You need to verify if power is reaching your front hvac blower when requested by the a/c blower controller. I hope you get lucky. If this is not for you, perhaps a few more detailed symptoms would be helpful. : )

Blower fan only works on high


CHECK THE HVAC CTRL FUSE.

WITH A TEST LIGHT CHECK THE BLOWER RESISTOR FOR POWER ON THE YELLOW, TAN, PURPLE, AND LIGHT BLUE WIRES. THE ORANGE WIRES CONTROL THE HIGH SPEED CIRCUIT. DO THIS FOR EACH POSITION OF THE BLOWER SWITCH.

THE BROWN WIRE ON THE HVAC CONTROL CONNECTOR 1 POSITION B COMES FROM THE HVAC FUSE 20 AMP. NO POWER ON THAT WIRE WILL CAUSE THE BLOWER TO NOT FUNCTION ON THE LOWER SPEEDS.
