77 HEATER PROBLEMS

1977 Ford Custom • V8 4WD Manual •

My 77 ford 4x4 heater is not working properly. You turn the fan on and nothing comes out but when you drive down the road you get a forced air heat. I changed the under the dash heater fuse. What could the problem be?

The switch itself.

Check to make sure the blower motor is getting power. If it is and still doesn't run, replace the motor. If there is no power, work back through the resister to the switch.
