I need to know the location of my blower relay. Already changed out the blower resistor, that did not remedy the problem (fan will not come on). Yes, I installed it correctly.


The blower relay is for high speed fan only most of the time . Do you know how to test electrical circuits ? It sure cuts down on buying unneeded parts . Here watch this video , this is a Chrysler vehicle . Don't know what you have , doesn't matter . They all work pretty much the same . I suggest you watch a few other trouble shooting videos as well .Is Chrysler Blower Motor Test subscriber requested video This next vehicle is a GM product , this one uses a relay for high blow only .

CHECK THE POWER TO THE BLOWER. IF YOU HAVE POWER BLOWER IS BAD..NO POWER? CHECK BLOWER RESITOR. I GUESS YOU ALREADY CHECKED THE FUSES. IF NOT START THERE

Blower fan not working


The resistor bank is bad for slow speeds, the switch is bad for high speed. In your test, you have voltage, but the switch wont carry the amps, to run high speed. Open circuits will not blow fuses. Replace both switch and resistor bank for all speeds. Make sure to clean leaves and trash from fan housing and see if fan spins freely.

REPLACE BLOWER MOTOR RESISTOR. IF YOU GET ONLY ONE CONTROL SPEED.IF YOU HAVE ALREADY REPLACE BLOWER MOTOR RESISTOR.BLOWER MOTOR CONTROL SWITCH BAD. REASON BLOWER STAY ON ALL THE TIME.FAN BLOWER MOTOR RELAY BAD.

I have only high speed on my ac/heat switch. have replace acdelco blower motor resistor 2 times already. works for a while and quits. whatelse do I need to check etc?.


If you have replaced the blower motor resistor block twice all ready, i would be replacing the blower motor itself. When the blower motor is drawing too much current it burns out resistors for lower fan speeds in resistor block, but doesnt blow fuse for fan. Also check for leaves and stuff in fan when removing fan.

Blower fan low speeds don't work. Can only get the fan to work on position 3 which is too high. What might have happened such that positions 1, and 2 don't work?


it is the blower motor resistor. I do not know off of the top of my head if it is part of the climate control unit or external for your particular vehicle. However the symptoms match.

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.

Heater/defrost/ac does not blow in my 2006 tacoma. worked this morning, parked at work, came out half hour later and would not work.


what has most likely happened is that a fuse has blown that is in your blower fan circuit. Check your owners manual, and see if there is a fuse to that system, if there is, check and see if it is blown. If it isn't, then the problem could either be your blower fan itself, or your blower motor resistor. Generally, when the blower fan goes bad, no speeds of the fan work. When the Blower motor resistor goes bad, usually only 1 speed of the fan works. Try the first suggestion i gave, and it everything checks out in the fuse box, then try all of your fan speeds. If one works, you need a blower motor resistor, if none work, then it is most likely your fan. Let me know how it goes and i'll do my best to assist you further. good luck.

My air conditioner/heater blower will not work on the 4th setting. Setting 1,2, and 3 do work. I have replaced fan speed switch and replaced the resistor. Any ideas?


You'll have to find the correct wiring diagram in order to trace down the fault in your system.. Once you obtain the wiring diagram you'll be able to see what else beside wire is between the #4 speed setting and the blower motor. My guess is you might find a high speed fan relay is triggered from the #4 fan switch setting, applying full battery voltage to the blower motor. If locating the appropriate diagram proves to be difficult you can try looking around the underhood and passenger compartment fuse panel to find a relay. Keep in mind not all relays are always in fuse boxes which makes the diagram important.
