76 K5 lower fan..no workie..please help
 

Nothing works at any speed. Checked for voltage at all points of the motor...nada. check for power at dash switch, nothing. Cant find any fuse marked blower or heater. and all fuses show power on both ends. was working fine this morning, left work tonight and nothing. I dont get it. any help greatly appreciated. Got an elk hunt coming up and no heater = no bueno!

I ant gotta clue.


worse case scenario, run a fused wire to it with a flip switch. Make sure you put a relay in it.

Check the ground as well.
