blower motor question

[1nine84GT]

I have a 2002 F-150 Super Crew (loaded) the blower motor has 4 settings and it dont work on the low or low-medium settings. It works on the medium-high and high setting just fine. I have owned the truck for 2 weeks now and It was this way when I bought It. Any Ideas on what to look for and check out ? Thanks In advance.

Should be behind the glove box, just fold it down and you should be able to see it.

Find the blower motor resistors, by the blower motor itself. Unplug it and ake a test light to each of the wires and make sure you get illuminaion when you change settings. I can give you a wiring diagram, but its not hard. Put it on setting 1 (low) and check to make sure you have power and the resistor on one of the clord plugs. Then setting 2 and check for power and so on. If you dont have illumination at the two speeds tha arent working, its most likely the switch.

You probably have a bad blower motor resistor, but it doesnt hurt to check the circuit first, since it's fast and easy.

So do I have to pull the dash to find It ? I looked behind the glove box and It looks like the dash covers everything up.

Thats what it looks like... Might be able to see it better if you pull the shield out under the passenger side of the dash.

Coupe, I will take It. Maybe I can swing by one day this week and get It. How much do you want for It ?

I think I found It. (99.9% sure) I didnt look on the bottom side of the dash the 1st time.
