Blower motor replacement

If it doesn't work on high speed it 's not the resistor. If you have a test light, pull the plug on the blower and turn the switch on. If the test light works then it's the blower motor. Make sure to test the power in all positions as you could have a two fold problem. If the light doesn't work then it's probably the control switch.

With the blower motor on high check the purple wire to the blower motor for battery voltage and the white wire for a 2 ohms or less to ground use the 200 ohms setting on the meter to check the ground. Let me knowwhat you find.

The purple wire were not going to be checking for ohms to ground. The meter will be set to 20 volts DC vikts scale. Put the key in the run position turn the blower fan on high ground the black wire of the meter. Hook the red lead of the meter to the purple wire terminal at the blower motor connector. You should see battery voltage? Sounds like you have a ground on the white wire. Let me know what you find so far we might have a bad blower motor control module.

Now measure across the two terminals with everything set the same key ac setting etc. What does the volt reading say?

Your welcome that explains it glad you found the problem.

Hey, how you doing today? If that is the original blower motor, My info shows you cut the blower motor out, utility knife. You access from underneath dash.

Make sure the blower motor is faulty before you do anything. I can't see what your doing, all I can do is go by the database. Also you can go to the autostore, tell them you want to look at a new blower motor for your vehicle. The hardware and instructions that come with the new blower motor should give you an idea. Tell them you just want to look at it right now, buy later, maybe. They always let me look at the part without buying, If I'm not sure about something.
