Out of the blue, the interior fan stopped working. I don't have A/C, just the fan. Is there a fuse for the fan, if so where is it. I do not have an owners manuel, Thanks , Dave

 

If your vent is working and the fans working, its not the fan, its the ac compressors problem. The first thing I would do is to see if it's full of R12/R134A and then check the high-psi switch by the accumulator. I've had to replace at least 4 of these on my truck. You can replace them yourself too. I believe there about $15 at Ford and it just spins off real quick and you install the new one just like it.

 

This is a non air conditioned truck? What kind of vehicle and model year? And yes there should be a fuse in line.

 

Yes, this is a non-a/c van. '94 E-250 straight 6cyl. cargo van.

 

Jeez, I need to start reading better.

If it's not the fuse, it's the fan itself. I'm not exactly sure where the fan is on a Van, but I assume its on the passnger side of the truck. Open your hood and you'll see fan cover. You can remove and replace the fan from there.

 

[updated:LAST EDITED ON 14-Sep-02 AT 11:26 PM (EST)]I don't know if the 94's use it but the older systems used to use a system of resister coils to control fan speed. There also was a thermal protecter in this same circuit that would cause an "open" if the resister circuit got too hot. These thermal protectors, actually a diode I think, go bad and poof...no fan. If a resister coil goes bad....poof, no fan. If the fan motor brushes wear out...poof, no fan. I think on the van the fan motr is accessed from under the hood on the passenger side. If you can find the connecter to the motor you can rig a jumper wire to the battery to see if it will run. First check the fuses in the fuse panel. If you don't know which fuse it should be just check them all. Let us know what happens. Oh, one other thing. Sometimes the connecter at the fan speed switch would burn up (melt)...poof, no fan.

 

But do you know if there is a fuse for the fan somewhere other than the fuse box under the dash or the main fuse box under the hood. I have checked all of the fuses in both boxes.
Thanks, Dave

 

Actually if the thermal limiter in the resistor opens up (goes bad), the fan will still work in the high speed setting only. The resistor is only for all settings below high.

 

You are correct about the thermal resister. Thank you. I guess with all the "poofs" I got a little carried away

 

Hi,

On my '92 there's a power distibution box located under the master cylinder. There you'll find a 60 amp fuse and a relay for the fan motor. When you turn the fan on the low amp circuit closes the relay allowing high amperage current to the blower. Test the wire going to the motor for power.

Good luck
