Fan/blower motor relay balast

A couple months ago I lost speeds 1 thru 3 on my blower motor and retained 4 & 5. I bnow have no speeds. I changed the dash head units and still no fix. I checked the blower motor itself by jumping it off the battery and it works fine. Could it be the goofy metel plate thing that i'm assuming is the go between, between the in dash switch and the motor itself. Someone told me that is the blower motor realy balast?

Look on the duct work near the fan ... you should see a connector that fits into the duct work...the part is held in be two or three screws. remove that part and replace it.

Blower motor speed not working


This is usually due to 1 of 3 possible problems.

  1. Bad blower motor resistor - attaches to blower motor and regulates fan speeds. Not uncommon to lose 1 speed at a time until you get stuck with only 1 speed
  2. Bad blower motor
  3. Bad heater control module - less likely but still possible the module is bad and the whole unit requires replacing

2005 gmc sierra heater fan quit working. I lost the fifth speed months ago and a couple of days ago lost the other four, the first day the fan would come on sometimes while driving then quit after a while...


1-4 speed are the blower motor resister . It controls all 1-4 speeds, also it's under the passanger side dash around fan, the 5th speed runs off a fuse the is located in the fuse box. It's one of those square fuses , not the relays but fuses. The resister will run $15 and fuse $5 . Good luck. I have replace these before

Blower doesnt work on all speeds


Step 1: Check fuse
Step 2: Change relay (usually can swap with another relay in the fuse box and try it)
Step 3: Check connection on switch
Step 4: Replace Switch
Step 5: Check connection on blower motor
Step 6: Replace blower motor

Chevrolet has a bad reputation for the connection and/or switch malfunction for the blower motor. I changed all 6 items in my truck in a 3 month span as all 6 appeared one right after the other.
Good luck.

2005 Trailblazer EXT. Blower speed control not working...


Problem with blower motor is the blower motor resistor. They are usually located next to the blower motor, a couple of screws and a couple of plugs and your done. Autozone sells them for around $30 each. Wipers you may want to check for relays under the hood in the fuse block. There may be 2 relays 1 for low and 1 for high. I have switched relays from other working accesories and got wipers to work. Sometimes bad connection.

The HVAC blower fan on my 2001 Pontiac Aztec stopped working on settings 1-3 several weeks ago. Last week it stopped working at setting 4 and today it stopped working all together. What is the most likely...


the blower not working on settings 1-3 is the blower motor resistor. this limits the power provided to the blower motor itself to change the speed. at setting 4 it is getting full power. since it quit on 4 also, i would still say the resistor needs to be replaced first, then see if the blower comes back. you may also need a blower motor. if you have a voltmeter you can just turn the switch to 4 and see if the motor is still getting 12 volts. if it is and doesn't run, it needs a blower motor too. if it's not, then its just the resistor
