Do you have a multi meter to do some testing?

Yes, I do have a multi-meter.

So fan position one and two doesnt turn on the blower motor?

Yes, that is correct; fan switch positions 1 and 2, no blower motor. Positions 3 and 4, the blower motor runs in a normal manner.

I posted the trouble tree let me know what you find.

Thank you for the troubleshooting tree. Now, I need some input on accessing the fan control switch and mentioned wiring without destroying the grill panel.

I posted how to remove the ac control.

Progress to date: Switch panel and switch removed. Did a resistance check on the disconnected switch positions and it appears to be working okay; that is a circuit is formed on different connector pins in each position, except off.

The instruction asked that the blower motor power and the blower motor resistor be disconnected for resistance check. I have been unable to locate either the blower motor power connector or the blower motor resistor.

I posted a diagram to show you where the resistor and blower motor is.

Mission Accomplished, partially. I located the Blower Motor Resistor removed it and found it be heavily rusted, flaking and one resistor coil disconnected. As a temporary fix, I connected the "floater" resistor coil to another having a common connection using a small gage solid electrical wire, holding it in its approximate connected position. All fan speeds are now functional at the expected manner, indicating the fan switch is functional.

I have also located a replacement Blower Motor Resistor on eBay. Would you have a recommended supplier?

Saturntech9, you assistance has been of great value and very much appreciated.

Thank you very much.

I get a lot of parts on ebay or www.rockauto.com for rock auto i have a 5 percent discount code if you need it
Also your welcome thats what were here for.

They have a ford motor craft one on rock auto for 22.

Sure, I will look at rock auto.com and would use the 5% discount number.

Thanks again.

Just looked on ebay they have the motor craft one for 24.61 with free shipping which would be cheaper then rock with shipping.

OK, all good!!! Will get a replacement part underway to me as quickly as possible.

Thank you.

Sounds good i would go with the motor craft one.
