Blower switch
Hi guys,
The blower in my wifes 99 expedition stopped working on lo-med, worked only on high. So I replaced the blower motor resistor and nothing happens. She now tells me that right before I replaced the high setting stopped working so I'm now thinking the switch might have went bad too. Can someone tell me if replacing the switch is an esy project, where it is located, dows the dash have to be taken apart? Might have to farm this project out. Thanks!
I should add that the expy had front and rear hvac. The back works fine, it;s just the front fan that does not work. Thanks!

did you check to make sure the connector the the resistor wasnt burnt? should be relativly easy to change out. according to the pic in my system, pull off the center bezel(large) and then unbolt the hvac head unit. unplug the old switch, install new switch, and put back together.

I am having the same issue as Crabster above. Just replaced the dash fan speed switch (it was real easy) but, it did not resolve the issue. Checked every fuse on both fuse boxes. I still have only the highest fan speed working. On a long trip that gets really irritating. Anyone have any other ideas?

I have the same problem on my 99. Fan only works on high. What is a resistor pack and where can I find it?
APS612, Did you find one? Where and how much was it?

I purchased it from the local Ford dealer for about $16. Make sure you take the old one with you. I was initally handed the wrong switch as others on here have noted. So save yourself possible return trip. Take the old one and compare. It took me about 20 mins to take it out and less than 5 mins to put it back in.

I pull the wire harness from my relay under the dash and I found to have extensive corrosion as well as one one of the connectors had shorted out and damaged the harness it has a connector on both ends of the wire but dealership is quoted me $75 for maybe a foot worth of wires and and a relay... looking at junk yards for the wires. even when disconnect disconnected from the relay blower still works on high!
