A/C blower not working

[lambertjp]

Had an intermittent problem with blower before. Changed out everything I can get to. Resistor, some wires that were messed up and then the three switch unit on dash ( fan speed, temp and selector switch) AC and heater works. Now blower doesn’t work at all! AC shops won’t touch it cuz it’s a 2000 and parts are hard to find. Any ideas? PS I’m not an electrician! Thanks

Have you pulled out the blower and tested it?

Yep. New one in. Hooked up directly to battery. Works great!

Check the connectors at the resistor and blower motor. They have a tendency to overheat and melt. This results in spread terminals and a poor connection.
