HI, im having problems with my platinum the a/c fan speed is stuck on high. the temp works and all the other controls. only the speed and the fan level on the HU change but the speed is still stuck on high. any one else having this problem?

 

I had the same problem happen on my previous '09 FX4. It ended up being a relay that was replaced under warranty.

Hope this helps!

 

Unhook battery and hook it back up.

 

Mine is doing the same thing.

 

Wife's crown vic had a resistor under hood in front of wirewall that was stuck. After a good whack it worked fine.

more times than not. resistor pack.
i just had mine replaced, this morning. its been 85plus and now getting into the 100's . and high all the time is fine until i try to talk on phone.
paid 132 for part and labor. i beleive part is 68.00?

i know i could have replaced myself. and would except if that was not it. then i would have been stuck with an un-useable part.

works great now.
