I had the same problem with mine and I replaced the blower motor, and still didn't work. The problem ended up being the blower motor control module. I have the auto temp control, so my replacement part was pretty expensive. Found a used one online fairly cheap. Hope this helps.

Check your ground wire for power take the control off and check and see the ground wire burn apart

I Have a 1998 Buick Rivera Blower does not blow i have power to the relay under the rear seat i have pulled the blower motor. by passed and motor fine no power to fuse left side of dash is there a rel


Not sure hat rely you are checking but the blower motor does. To have a relay in the rear fuse block. The fuse you're checking protects the HVAC computer. The HVAC computer uses that circuit to monitor the voltage going to the blower motor.

The most likely problem is the blower motor resistor, aka blower motor module, blower motor speed control. It is typically located near the blower motor. The red wire is power from the battery and should be there all the time. Black is ground. Purple is power to the blower. Grey/black is the speed input from the HVAC module.

1992 buick le sabre blower motor resistor location


If your Buick has "automatic HVAC" (you set a temp and it stays there) you do not have a resistor but a electronic controller. The common failure on these is the blower stays on when the key is turned off. In either case, the part is usually located on the engine side of the duct work. it will have wires/connectors and be in the airflow of the blower.

The brown wire at the speed switch is the power wire. Powers is then directed to the blower motor resistor throught the orange, lt blue and yellows wires. The blower motor receives power through the orange wire. Check for power at the fuse with the key on. If there is no power the problem could be the ignition switch or the wiring in between the switch and the fuse block

My heater blower will not work on my 2002 Grand Am. I have checked the two fuses on each side panel and put a meter and even a new blower motor and no reading or power to the new motor.


Power for the blower starts at the fuse, goes thru the HVAC control panel, then the resistor block, then thru the high speed blower relay, then to the motor.
You should have voltage at the resistor and at the relay.

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.

My 98 Buick Le Sabre heater blower works sometimes and sometimes it doesn't. You just never know.


Sounds like a bad heater control switch OR bad connector to the motor itself. I'd try your local salvage yard or EBAY for a replacement switch. Good Luck. . .

Blower motor won't work, even with new motor.


Hello Travis.
If yours is dual zone, I believe the resistor (blower control module) is a solid state. Did you check it using the fan speed selector and test the voltage output on the purple wire?
The gray black wire going into the resistor is a variable voltage output from the heater control panel. This signal is amplified by the resistor/blower control module.
The black wire out of the resistor also needs proper good ground.
There is a fuse in the underhood relay/fuse panel that feedback from the resistor output to the blower (purple wire) is also fed back to the heater control panel. Verify this fuse is good.

When blower motors go bad they will often absorb a lot of electrical current. This current has to go through the blower control/resistor and will often burn them out due to the heat developed from the high current load.
These resistors are also mounted in the airflow out of the fan motor to help cool them so if the fan is still drawing current and not blowing the resistor overloads and burns it out.
Not sure how you tested the resistor but I suspect yours is faulty.
If you would like more advise let me know.

Defroster / heater fan won't shut off /1995 Buick Le Sabre


Moe, I think you hi blower relay is bad. With this I mean the contacts in the relay are welded shut and you should replace the relay if the blower is on high all the time. Do this by removing the black plastic cover right behind the engine and removing the relay all the way to the drivers side of the relay bank. you will have to insert a small screwdriver under the relay and bend the little tang that holds the relay in place. then slide the relay out towards you and remove the green lock tab and unplug the relay from the wiring harness. if the blower finally stops then just insert a new relay in its place and reassemble in the reverse order. Good luck.

The blower motor for the heater/AC does not work after replacing it. All fuses are ok


OK, history would be nice. What a/c do you have, Manual or Auto/Electronic? All Speeds? Why did you replace the motor. If the fuses are ok, did you check for power at the motor? if it has power and ground, it HAS TO WORK, or the motor is bad. If you did not check for power, then if you have Manual A/C, Turn blower switch to HIGH SPEED, check the PURPLE wire (at the motor), if it does not have power, then check RED wire at the BLOWER RELAY. The RED wire should be HOT AT ALL TIMES. If the Red Wire is HOT but the Purple wire is not, then check the ORANGE wire at the blower relay, it should be hot (if the orange wire is not hot you may have a bad blower switch ). If the RED and Orange wires are hot, then the relay may be bad, You can by- pass the relay to see if all is ok but connecting the RED AND PURPLE WIRES. The blower should run at high speed. I dont want to look at the Electronic A/C, its more complicated and I dont want to waste time if thats not what you have.
