fresh air blower, where's the hot lead? Options

[jr91472]

Didn't want to hijack and my issue is a little different so........

Can someone explain to me where the hot lead is located on the fresh air blower switch in the dash. All I can find is one red wire that goes into a small lamp socket next to the dash board lever.

I have three white wires (w/ stripes) that control the fan speed. Then one ground wire on top of the switch unit and another ground wire on the bottom.

This seems consistant with the wiring diagram, but I cannot figure out how this circuit works. The only place I can find 12v is if I pull the lamp socket out and probe at the end of the red wire. Once I put the lamp socket back in place, nothing. Is there some kind of contact inside the lamp socket?????

btw, the little light bulb is burned out, don't know if that matters or not.

thanks

Maybe I am confused with the other thread. Just reach up in behind the blower housing on passenger side. pull the square plug out. Red wire is the 12V to run the blower fan.

The light bulb which indicates the fan is on has nothing to do with making the fan run.

The other thread said the fan ran in low and medium speed so obviously that fan motor is good.

My fan was stuck. I pulled off the hose coming out of the drivers side fan housing and used a stick to try and turn the fan. Stuck stuck.

Pulled gas tank and eventually fan housing tore it apart and used PB blaster to free up the bearings. then electrical contact cleaner to get all the oil and grunge out of the motor. Runs all three speeds.
