No power to the blower motor at any speed setting, Doesany one have a wiring diagram for a 1973 coupe? Or where can I start looking for the power supply. Thanks Den

 

Bigdenny, welcome to the forum-you have found a great family here. I'll try to give you a little help on the blower wiring from my '78 wiring schematic. Main line voltage comes from the ignition switch then on to the fuse block where it's distributed to several accessories, through the heater or A/C fuse then up to the blower speed switch, from there out to the speed selection resistors mounted on the heater or A/C plastic housing then to the blower motor. Have you tried putting a jumper directly from battery positive to the motor to see if the motor is working? Also check for a clean tight ground, you can use a jumper wire here also. Let us know how your doing.

 

Welcome to CF!
Sounds like 78buckshot has it covered.
