My truck, 1985 F250 6.9, is one of the ones that has the dealer installed air in it. It has a seperate blower for the heater and air conditioning. The resistor for the air conditioning blower went south and will only run on high. I figured that the one for the air would be the same for the heater so I purchased one that the parts house lists. It does not work. The parts house only list one resistor for that truck and that one works fine on the heater blower. Has anyone else ran into this before? If so where did you get the correct resistor for the air conditioner blower?
Thanks for your help,
Rodney

There are 10 dealers that still show to have one. none in "LA"
I would see if there is a ID number on old part. Maybe I could get this for you.
