    What year and model? I have a 99 Deville. My blower motor has went out twice now. The motor and resistor are all in one. New is up to $200. Used from a salvage yard will vary as well if you can put it in your self. I have found tons of info from everyone in the forum. Just look around and read.

    Run a jumper wire from the positive battery post to the power wire on the blower motor. does it turn on? If not, replace the motor.

    Discussion includes similar problem, including voltage checks on existing blower. You will need a volt meter. DO NOT CHECK CONTROL WIRE TO RED (HOT) WIRE, this will send 12+ volts thru control wire, possibly, most likly, frying your blower.

    Do check red to ground, even with ignition off, key removed, you should have battery voltage (12+ volts DC) on red wire.

    Check wires with plug attached to blower by running the leads thru the back side of the plug, just follow the wires into the plug. Don't worry, its a rubber moisture shield you will be poking thru.

    Put red lead on middle wire (control wire) and black lead either on black wire, or engine ground somewhere, or even the negative car battery terminal.

    Run the blower modes thru their paces. Set "hi" and "lo" , checking voltage at control wire.

    As the link describes, you should see a voltage change at the control wire.

    See Rangers posts on the subject as well, he was a big help when I was troubleshooting.

    I, ultimately, had to replace the blower motor, which on my 99, was on the firewall under the hood. I'm no mechanic, and it wasn't too difficult a job. Lots of steps, and you will need lots of patience.

    Use this site to do your homework first! I can't stress that enough. I spent a few days reading threads on the subject. There is plenty of help and helpful people here!
