1987 Chevy El Camino V8 Two Wheel Drive Automatic
In the past year I have had 2 blower motors replaced in my 87 ElCamino. The work was done at a local dealer. Now the third one has quit. What would be causing the failures, and how do I check if I am getting power to the motor? I have replaced the resistor, the control module, the motor itself, and two of three switches on the inside. The only thing I have not replaced is the fan speed switch. I pulled it out and there is no visible evidence of arching etc. I have a brand new motor I installed and I have and it will not work. HELP!
