Fan speed - 2 lowest settings won't work
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.
