Fan speed - 2 lowest settings won't work
Hello all,
I have a goofy one. The two lowest fan speeds aren't working on my 2000 F150. The two high speeds do, there is a definate difference between speed 3 and speed 4 (high). Because more that just the highest speed worked I thought it wasn't the resistor block and replaced the switch, same problem. What do you think my next step should be? Replace the resistor block? Its a cheap part, $18 bucks, so I might give that a whirl, beyond that I'm lost as to what to do beyond that? Fan?
Thanks in advance.
Matt

I did this today/yesterday.
Perhaps you will have better luck b/c yours insn't as old as mine (87), but here is my suggestion...... buy both the resistor (about 20) AND the pigtail/plug (about 18). In mine the pigtail/plug was totally shot and one of the wires melted. Have also read of other with similar experiences on this board.
IMO, it is better to have to return to the parts desk at your convenience to get money back... opposed to having to go back right in the middle of the project to spend more money.
Good news.... it is an easy fix.

Thanks to all who replied. I finally got around to doing this last Saturday. It was indeed the resistor block, half of it crumbled in my hand it was so corroded. Replaced it and now enjoy 4 fan speeds again.
Now I'm going to have to read those dampener posts as my temp control is not what is should be.
