Electrical problem
1999 Ford Expedition V8 Four Wheel Drive Automatic 128000 miles

blower motor doesn't work, but fuses and relays check out. There is no power at the motor. What could be wrong? Maybe the resistor? Thanks Rick

First thig to check are the fuses, both in car and under the hood. If OK check for power going to the resistor. If OK replace same, if no power, run a self diagnostic, and post the resulting code. Have the engine temp at least 120 degrees, and the internal cabin temp between 40-90 degrees, then turn the key to on, press FLOOR and OFF at the same time, then within 2 seconds press AUTO, the indicator will have a small slash rotating around, the test takes a minute or two, if any codes are store, they will display shortly! To exit self test, press the BLUE, cooler button this also retains error codes, To erase code and exit, press defrost, choose one of these before you power down the system.
