Well it is 80 deg, in N.E. Ohio, but gettng ready for cooler weather...M y 1986 F-150 [w/o air conditioning] lost control of the low and med speeds on the heater blower. Of course I know the High speed is wired direct and will [does] work. I pulled the the resistor and suspect it. [blower motor was siezed up f,rusty from sitting all summer] I freed up the blower motor, works fine, but WHERE CAN I GET A NEW RESISTOR? Local Ford dealers don't have one that old. I don't really want one from the bone yard if I can get a new one. Any help appreciated!

 

I got my last one at advance. they are the same from 80-96/ try rockauto.com too.

 

Thanks dustybumpers: Ive tried them, they only have resistors for trucks with HVac factory air. These resistors are different,[4 speeds] not standard [NON AC]3 speed heater blower.

 

Can you take the resistor to radio shack, and match it up? Just solder that one out and the new one in.

 

Radio shack won't work, too much power.
These are open air wire wound resistors.

I do not have A/C and had no problem locating one in the aftermarket.
Let me see if I can find a part number

All my trucks, 82, 86, 89 90,93,94and 94 Centurion, have 3 speed blowers. all but the 82 have a/c. The 86 has aftermarket a/c, and uses a stock heater box. I think the part number Chris gave you will work.

 

Just ordered one from Horizon Ford !
