2007 F150 Cabin Blower Problem
Hi
I did several searches using the keywords that make sense to me, and found nothing about the problem with my '07 F150 super Crew.
I thought I had an after market service manual, but I guess not and I'll have to get one.
The other day, I noticed that the cabin blower works fine on speeds 1, 2 & 4 but while on speed 3, it blows the same as speed 2.
Based on some of what I read, it seems the different speeds simply switch between different series resistors. That being said, unless the speed-3 resistor increased to a similar value as speed-2 (which seems a bit unlikely) I'm a bit confused about this malfunction.
Also, where might I find this speed control board?
Any help would be appreciated..
Thanx

I had the same problem but it was #1 speed that wasn't working . It's an easy fix, the circuit board is about $30 and it is located on the passenger side down at the fan motor. You will see an electrical connector with 2 screws. Simply unplug it and remove the screws and install the new circuit board. If you search I think there is a forum that explains it with pictures. Good luck !

I hit three different auto parts stores and their computers suggest a haynes manual. That particular haynes manual only covers pickups to 2003 and expeditions to 2009.
Am I missing something?

Yeah, the symptoms didn't seem to call the resistor board to me. I replaced the fan speed switch and all is working fine now.
Picking up trim removal tools from a harbor freight REALLY makes the job much easier and does not damage the interior. Only $6.50 for a 4-piece tool set.
