Only have 1 speed (high) on fan motor and winter is coming! Changed the main speed selector switch -did not fix the problem. then set about to find the main fan resistor near / behind the glove box. found several items, disconnected 1 at a time and tried fan after each one--did not fix the problem.

ANY SUGGESTIONS???????????????? No wise cracks PLEASE!

 

It definitely sounds like the resistor assembly. It is screwed into the front of the fan housing in the engine compartment. The housing is in the back passenger-side corner of the engine compartment, behind the coolant and windshield fluid resevoirs. You should see a connector with a few wires going into the housing, with a screw on either side of it. Carefully pop off the connector, take the screws out, and you can pull out that corroded resistor assembly.

The ford people told me the resistor was in the cab behind the glove box -from what I can tell your saying it's in the engine compartment.


THANKS--I hope I can help someone else on this forum!

 

It may be in different places on different years, but I'd expect my '98 and your '00 to be fairly similar, if not exactly the same in regard to that system. I'm fairly certain that we have the same heater plenum.

By the way, just disconnecting it isn't going to "fix" the problem. I'd have to check the wiring diagram again, but it might not even change the current performance (it may still work in high after you disconnect). You'll most likely need to replace it with a new one (I think it was about $10~$15 at the dealer).

Jim needed a new plug and resistor both burnt out. Took a tad bit , but I got it working-just in time for the cold weather and hunting season-Thanks for the help!

Disconnecting /taking it out it did not stop the HIGH speed from working

Glad you got it fixed. I sort of expected that the HI setting would work even with the resistor out of the circuit since it is bypassed for HI anyway. Interesting that the plug was "burnt out" as well. I had to replace the connector as well, but that was because it was corroded to the resistor assembly so well that I broke it when I pried it off.

Can someone take a picture of the resistor and post it so we can see what we're looking for

 

I think this video might compliment an image. It helped me to better understand this post :


(I'm reading as many posts as I can relating to a/c issues. My current issue is detailed on my profile)
