heater/ac blower motor intermittently working
 
04 1500 5.7
Blower motor is intermittently working. Plugged in a new resistor and motor doesn't help. All wireing is good. Anything else to check before replacing control unit?

All help is greatly appreciated

A melted ignition switch and connector is a common failure that will prevent power from making it to the blower motor. Check the dark blue wire at the blower motor connector with the key in the run position. You should have power and the connector should be clean and show no signs of melting. If you're OK here, pull the steering column covers and check the ignition switch connector for signs of melting. New switches and connector pigtails are available from a dealer.

Ordinairly a great idea, but there's not one to check with this setup.

Did you check the dark green wire at the ignition switch yet?
