'94 E150 AC/Heater blower problems

[jsmorris]

I have recently run into a problem with the blower motor on my 1994 E150, 300ci. The fan would not blow in the three slower switch positions, but worked fine in the high position. This week the high position started acting up, and even the MAX AC position does not blow much at all. It is a soft enough blow that it is less air movement than the original lowest blowing position.

I had a problem like this on my Wrangler, and it was fixed by replacing the Blower Motor Resistor and the actual knob switch. Does this sound accurate? Any suggestions on how to find the resistor?

I am going to take the dash apart and jump the connector for the switch to see if I can isolate the switch and confirm that the problem is elsewhere in the system.

Thanks, Joel

Had same rpoblem...mine was slide switch defective, replaced now nothing so I have to locate inline fuse. Suppose to be on either side of fender liners by firewall....still tracing. Hope yours easeier.

my 99 e-150 needs the same thing my local mechanic said its a blower motor resostor but wanted 300$ to do it so i just deal with it its a hassle but not worth it in my opinion if its to hot in the winter crack the window if its to cold in the summer crack the window but its probably the blower motor resistor

So i decided to get a second opinion on it from my friend (whose also a mechanic) and he said it wasnt the resistor at all it was a bad selector switch so about 25$ later its all good now and works like a charm thanks for the help. happy holidays
