Blower Fan Speed Issues
Hi everyone,
I have an '06 F-250 with the Automatic climate control system. A few days ago, the fan speeds appears to stay at a very low constant speed until you turn the fan controller to the top position. The fan speed display shows 7 horizontal hash marks represents the fan speed to the fan goes to high only when I set it to position 7. Everything else appears to work correctly, ie. it will switch from vent to defrost to feet only. Any ideas where to start with this?
Thanks

I may not understand you correctly, but it sounds like you need a new resistor. Are you saying that the fan only works on very low no matter what speed you adjust it to, with exception of the highest setting?

In searching other threads, the resistor pack for an Automatic Climate Control system is:
# 4C2Z19A706AA
or Napa # BR-348
Does that sound right?
The location for the resistor found reading similar posts is:
And, it is the item located inside the housing, just to the left (drivers side) of the fan motor and slightly behind the AC dryer where electrical fittings are plug in. It is bolted in with 2 - 5/16" lug screws.

Mine did the same thing, that sounds about right where mine was but I opted to let ford buy the part for me with some other small warranty stuff I had done so I'm of no help on the part number... but yes it was the resistor.
