Gravelrash 36 Posted November 24, 2021 Hello, im chasing a problem I’m having with my XG. the blower fan works on 1,2,3 and 4 speeds, but the fan actually slows down in 3 speed.. I have replaced the fan resistor with several others as well as measuring the resistance in all. All were the same. I have measured voltage and the fan plug and have voltage bar the plug in all 4 speeds. Scratching my head as to where to head next…. Share this post Link to post Share on other sites
deankxf 20,231 Posted November 24, 2021 i would only assume it can be the wire possibly half shorting out or cut through to one strand? screw from stereo screwed through it? not something i've seen before.. Share this post Link to post Share on other sites
2redrovers 21,372 Posted November 24, 2021 Worn fan bearings/bushings? Maybe on 3, the rpm is just right to make it wobble and slow down? Just a thought. Share this post Link to post Share on other sites
deankxf 20,231 Posted November 24, 2021 switch itself could be dirty also.. could spray some CRC/WD40 in it and turn it on/off 50 times and see if it comes good 1 2redrovers reacted to this Share this post Link to post Share on other sites
Gravelrash 36 Posted November 25, 2021 Is the XH fan motor the same? if so what I plan to do is plug the fan in and hold it, if it works on 3 I’ll then start to pull the dash out. though about the dirty switch scenario but I have good voltage on all speeds.

Gravelrash 36 Posted November 27, 2021 Problem found. replaced the fan speed switch and is now as good as the day it left the factory. 3 bear351c, 2redrovers and deankxf reacted to this Share this post Link to post Share on other sites
