blower fan quit, help!

[KSommer]

wouldn't ya know it, as soon as i pick up a r134a conversion kit , the blower motor quit :{ . where is the power for this thing? the fuse checked out good, but is there a fusible link? where is the resistor pack that tells it to run on med or low? yes, i jumped 12 volts to the fan adn it came on full bore, but i wantto get it right. if i can get the air in my truck to work, i'd never have to go home.

thanks, kent

bad switch

Most likely. They do give trouble and if the motor is running with a jumper, you (probably) have a bad switch. I have replaced a couple. The guts are right behind the switch lever.



Dig in.

Resisitor pack is on top of the air box under the dash. The power should run thru a fusible link on the driver side fender. I just replaced mine and I believe it was the orange wire.



The same link runs the electric windows and its a pain when the blower doesn't work, the windows don't work and the temps get over 100.
