How can you test an AC Blower motor on a '97 Cadillac DeVille with the automatic air control system?
Red and black wires are +12- volt, jumper the gray wire to ground to test.
Why do I have no power going to my blower heater motor on my Jeep Cherokee 1996?
PossibilitiesBlown fuse, defective Blower Motor Resistor Pack, defective blower motor speed switch, (Doubtful), disconnected or loose wiring, and lastly a bad blower motor if it has power and will not run. Easy enough to bench test the blower motor. Its accessed from the passenger side of the engine compartment. .Move the wash fluid reservoir out of the way (just unbolt it, leave hoses attached) and there are three 1/4" bolts holding the motor in place. Might need to pry it out after you have the bolts removed due to the gasket sealing.On the bench, clamp the motor body in a vise such that the cage can be manually spun freely, then apply 12 volts to the connector.
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?
What is needed to perform a no load bench test?
A bench and no load! Whatever you are testing has no load. It might be a generator or a motor for example. If a motor it wouldn't be connected to anything. If a generator it would have nothing plugged in.

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.
How can you check to see if the heater blower is bad on a 1999 grand prix?
You can test your heater blower motor by connecting a ground wire to the ground. Connect a power wire, from the battery to the positive post. If the blower motor turns it is working, and if it does not it is bad.
What causes the AC Heater blower fan to stop working on a 1999 cavalier?
Check the fuses.If not the fuse, test the resistor down by the blower motor.
