You need to replace the Fan Motor Resistor assembly under the dash. Cheaper to by direct from the dealer, than aftermarket. 2006 F150 Ford part number is 3f2Z-18591-AA this tells me it fits from 2003 and up

Just finished changing blow motor resistor on 2006 F150, drop down the glove box by pushing in on pass side to release stop block, the resistor is right behind it, release plug by pushing up on the plug tab, take out the 2 8mm bolts remove and install, takes about 10 minutes max

my 1997 ford truck a/c blower stopped. I check and replaced the fuses. I was driving down the road with the a/c on and the blower just stopped with no warning.

Is this an easy fix or a costly one?

i have a 2003 ford f150. my air works fine untill i hit the accelerator and the air stops comeing out of the air vents and sounds like its in the vents is that the blower resistor switch going out or what please email me and let me know thanks.

I have a 2001, f150 2dr with a v6. When the a/c is going and there is no load on the engine it blows from the correct vents. When I get on the gas and get the RPM's up, the air switches from vent to defrost. I assume it is a vacuum problem but not sure where to start.

2003 Ford Expedition - suddenly the heater blower fan switch stopped working on 1, 2, and 3 speeds, it only works on the 4 (high speed). Looked at replacing the switch, but can not figure how to get to it. Then read on this site about possible fan motor resistor, which should I try to fix first and how do you get to the resistor?
12/28/10 12:39

#1, #2, and now #3 settings do not blow air. #4 does work. It's been a progressive problem beginning 2 years back. What part needs replacing? Thank-you

You all should of got a dodge. My heat works fine
04/03/11 19:14

When I start the 1997 f150, the ac works and blows cold air, then less than 3 minutes, it starts blowing warm air and only gets hotter. If I turn the control to vent, the air is a little less hot, but still feels like an oven at 400 degrees. The fan speed settings work, the freon is full. It is as if the heater takes over the AC. Can not ever put on vent to get air circulated as the longer I drive, the hotter the air coming out becomes. - any solutions? - Thank you

I have a 2001 Ford F-150 V-8 4.6L. The blower does not work on #1 & #2 but works fine on #3 & #4. Is the a blower resistor issue?

Have a 1997 Ford F150. Fan works great but can't get any airflow from panel or floor vents despite where I set the selector switch. I do get air flow through the defroster where ever the switch is set.

Thank author of this post/comment"blower motor speed controls"

Help! Need advice on the speed controls for the fan motor on my 1997 F150. Only works on speeds 3&4. Is it the hole selector control unit or is it a couple of vacume switches.
