The resistor is located behind the glove box and is held in place with two screws. Remove the glove box (approximately 10 screws) to gain access to the core housing the resistor. You'll see a connector with three wires attached directly in front of you. Remove the two screws securing the resistor to the core. Should have a number of prongs (heat sinks) protruding from one side.
it is probley not the blower switch. if your fan runs on 3,4 and 5 it is your blower motor resister.
The blower resister could be bad, or the blower switch could be failing. Check the resister first, it is commonly mounted at the rear of the blower housing under the hood.
You can find the 2004 Nissan Maxima blower motor relay switch beneath the passenger side dashboard. The blower motor relay switch will be behind the glove compartment.
My first guess would be the blower motor resister. My second guess would be the switch and or plug into the back of the switch.
Check the fuse and relay to start. If these are ok, then check the blower switch, the resister, then the blower motor itself.
Most likely the resister is burnt out. When you use less than full blower, the blower speed switch shunts the 12v power though a resister to drop the voltage to the blower motor, slowing the blower speed. When the multi-speed resister is burnt out, it is, 'open circuited'. So no electricity can pass though to the blower. When the blower switch is on 'full', the resister is bypassed, allowing full power to the fan motor for maximum speed. It should be located under that dashboard in most vehicles. Just trace the wires from the switch to the resister. Warning: a working resister can get very hot when power is going though it.
Start by checking the Audi's blower motor fuse. Check the blower switch, resister, and lastly, check the motor to find the problem.
You can locate your blower motor relay switch by looking at the diagram in a service manual. The blower motor relay switch should be below the dashboard on the passenger side of the passenger compartment.
Your blower switch sensor is out. Replace it!Then all the speeds will work
Check the blower resister and then check the blower motor switch..
Check the following................ 1. Power and ground to the blower motor. 2. Blower resister. 3. Blower switch.
Replace the fan blower resister
Either the switch or resister network has failed and needs to be replaced.
Only for the high speed blower function. The lower speeds go thru the blower motor speed resister.
The most common cause of the heater blower being on high only is the blower resister failing. The second most common problem is the blower switch going bad.
I hope you checked the fuse.
Blower motor NG. Blower motor resister NG. Blower motor fuse NG. Blower motor switch NG.
if you lost one or two fan speeds you need to change the blower motor resister. it sells for around $60.00 at a dealer only.
check the fuse, the relay, the switch and the blower motor resister. If these all check out could be the blower motor its self is faulty
Check the blower motors ground and power in the truck and the blower motors resister......
blower motor resister is bad
The blower motor resister is usaully located close to the blower motor, either under the dash or under the hood on the firewall. It all depends on your year, make and model. i have a 2004 trailblazer
If you only have high speed I would blame the blower speed resister. If you have no speeds and the fuse is good, I would blame the blower motor or the switch.
The heater blower motor speed resister is burned out.
Not knowing what year S10 you have, you can generally find the blower motor high speed relay nearby the blower motor on the firewall. The resister for the other lower speeds is also found close by the blower motor.
