Question about 2000 GMC Jimmy

1 Answer

The blower motor only works on high.

I replaced the control swith there was no change, and I also repalced the relay/resistor and no change I checked for voltage at the motor and as i predicted I only got a voltage reading on high.

Check and see if all your wires have good connection and if that's not it you may need a new motor

Replaced the resister and blower motor still nothing what next


Test for current to motor. If none you have either a bad fuse, bad switch or bad wiring. Nothing else left.

Blower motor


I'm showing a blower relay and a resistor used on models with manual ac control.
The blower motor is grounded and the fan switch provides power thru the resistor. So you have a 40amp blower fuse that handles high thru the relay, then a 30amp HVAC fuse that powers the blower thru the fan switch.
Do you not have power from the resistor to the blower motor on the purple wire ?

1992 chevy C1500: Heat works on low speed, no medium, and high only works intermittantly.


On any other vehicle it sounds like the blower fan switch.
The fan switch provides power or ground to the resistor and there would be a high speed blower relay to bypass the resistor.
But in your case the fan switch is part of the controller.
I don't have a diagram for a 92 but the 94 model shows relays for low medium and high speeds. Each relay gets power from a fuseable link. The high relay gets power thru the low relay if the low relay is not engaged.
If you have the model with 3 relays you may need to check them.

1995 GMC Sierra fan blower not working.


In the beginning you should check for voltage and ground.
The 50amp fuse marked AC powers the blower motor and the motor is grounded.
The high speed relay bypasses the resistor. So you should have power coming from the fuse and thru the high relay. Then the resistor for the other speeds gets power from the heat and ac control module which also controls the blend doors.
You may need a shop manual or repair book to get the diagrams.

Blower motor only works on low and medium on 2007 dodge nitro


You replaced the resistor and WHAT relay? The blower motor circuit on a 2007 Dodge Nitro does not use a relay.

The blower resistor gets it's power from the A/C - heater control unit.

If you check for voltage at the blower motor resistor connector (Key on, relay disconnected), the DARK BLUE/GREY wire should be hot when the control switch is on HIGH. The DARK BLUE/VIOLET wire should be hot with the switch in the MEDIUM 2 position.The DARK BLUE/ORANGE wire should be hot with the switch in the MEDIUM 1 position. The DARK BLUE/BROWN wire should be hot with the switch on LOW.

If any of these are not as stated above, then you either have a bad A/C - heater control unit, or faulty wiring between the control unit and the resistor.

I only get the fan to work on high speed, the lower speeds do not work


Hi!!
The Blower Motor Resistor also called Manual Temp. Control resistor), is fried, replace. The price with floor console $25 and without floor console $65. here is a pic.

the resistor is located on the blower motor housing, fastened by two screws. It is the part where the electrical plug connects, the plug on the pic. goes to the blower motor.
A HELPFUL - 4 THUMBS rating for this solution would be greatly appreciated. Thank you for using FixYa.

The resistor will cost you 12 dollars at your local dealership. It's located under the passenger side dash and is very easy to replace. The resistor installed at the factory is defective and the new one from Mopar is the correct resistor. It would be worth you while to replace it now while you're working on the blower motor. The blower should still work on the high setting, even with a bad resistor but, replacing the resistor may fix the problem.
