Default fan switch

Fan does not work on my '00 f150 at any level, checked fuse they are ok, can anyone tell me how to change the switch at the dash.
Thanks Don

Have you tried high speed?

Yes Bert, I've tried all speeds and all settings and get nothing, figure it is the switch but not sure how to remove it, I'm guessing just pull off dash and it is right there but not sure?
Thanks Don

It's been a while, but you are pretty much correct. Carefully remove that dash trim around that area, pretty much use your fingers to do so. Don't remember which spinner screw driver, red maybe? I removed mine in the parts store parking lot, it wasn't the problem, so I returned it right away. That was the day I learned about blower motor resistors. Check all the fuses?

Check your fan control resistor first!! Its a much more common failure mode and easier to to replace then the HVAC switch. See this http://www.f150online.com/forums/art...igh-speed.html

Check your fuse #23 Blower motor fuse, then your fan switch, since you have already stated that you have NO SPEEDS. You can test resistance on your fan switch, I found it easier like I said earlier to test a new one while at the parts store. Replacing the Blower Motor Resistor is easy also like the last poster said, and yes they are quite a common failure due to the moisture in the fan box causing them to corrode.
Blower Motor Resistors will loose lower fan speeds as they start to fail, The High Fan Speed bypasses the resistors on the board, still allowing for HIGH SPEED fan operation.

Start with you Fuses, working your way down the line
(fuse, fan speed control, blower motor resistor, blower motor)

I have seen your conditions caused by the electrical connection at the blower motor resistor being corroded. Unplugged the connector, sprayed it with electrical spray cleaner and it was good as new.

A Haynes Manual walks you through testing procedures, well worth the 19 bucks, cheaper than throwing parts that aren't needed.
