How do you test a resister in a blower?
To test the blower motor resistor, unplug the resistor connector. Each blower motor switch input terminal on the resistor must have continuity to the resistor output terminal, which is connected to the circuit going to the blower motor. If the blower motor resistor continuity does not check OK, replace the faulty resistor.You need a multimeter to test the resistor block and there should be continuity between all terminals.
The blower motor on your 1990 ford aerostar seems like it only works when it is on max ac how can you get it to work on the other selectionsshould you replace the blower motor or is there a wayto test?
If you are saying that the blower motor only works on the high speed setting, then the Blower Motor Resistor is defective and needs replacing.
What causes the blower fuse to instantly blow in a 99 Chevy blazer?
Short in the circuit somewhere. Try unplugging the blower motor, closing the circuit with a test lead or test light, and seeing if it blows then. If not, the problem would seem to be in the blower motor itself.
How do you determine if the heater blower switch or heater blower motor is bad on a ford 2002 crown Victoria?
You can unplug the blower motor and run a jumper wire to test the blower motor. If it is grounded through the plug you'll have to run a ground wire to it also. Blower Motor tested good. The Problem was the Blower Motor Controller which was located on the firewall just below the Heater Hoses. Thanks for responses to question.
How do you test blower motor resistor on a 1994 Toyota pick-up?
Remove and test with an ohmmeter Explain how to test with an ohmmeter?
Why is the heater blower not working in my 2001 Pontiac bonnevill?
Blower motor fuse is blown. Blower motor resistor burned out. Blower motor switch bad. Blower motor bad.
Where is the blower motor on a 1999 volkswagen beetle?
Blower motor: remove the glove box and you will see the blower motor and blower resistor.
When the blower does not work on all speeds is it the blower motor?
usually the blower motor resistor pkg. located on or near the blower motor
Your ac want blow how do you fix it?
If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.
Is the blower motor resister for a 97 Cadillac Seville in the blower motor?
It's close to the blower motor.
What is the purpose for the relay fuse for the blower in the 1993 Cadillac deville?
The blower motor fuse protects the blower motor electrical circuit. The blower motor relay operates only the high speed function of the blower motor. The blower motor speed resistor operates the lower speed functions of the blower motor.
Where is the blower motor for the heater located in a 1990 Ford Thunderbird?
Blower motor is usually behind the dash on the passenger side. Try removing the glove compartment to access it. If the blower isn't working, it could also be the resistor block (more likely to burn out than the motor itself). One blown resistor could keep the blower from blowing at all. Check that first (look for scorching and test with a test light). It's a pretty easy replacement and if the blower is not getting current replacing the motor won't do you any good.
