Bower motor not working.
Hey guys.
For the past few months my bower motor will stop working. It could stop while I'm driving. Or not work when i start the truck, then start working while I'm driving down the road. When it was working it worked fine. It had the different fan speeds like it was supposed to. It would just not work at all, or work fine.
Now it doesn't work at all.
I checked all fuses, and swapped the relay for the windshield wiper relay that i know works and still nothing.
I unplugged the blower motor and put 12v to it and it didn't work so i thought i found the problem. Took out the blower motor put power to it again and it spun just fine. Plugged it back into the harness and it worked other than no low speed. Flipped the switch back and forth, then low speed worked, up to high, but no difference between speed 2-3. Put it all back together and it seemed like all the speeds were working fine.
Day later, won't work at all again.
Any input would be awesome. I'm a little lost, and would like some help before i just start replacing stuff.
Thanks in advance.

My blower intermittently worked at all speeds. The other day it stopped worked....who knows, maybe in the morning it would have ran again....but I just replaced the motor. Time will tell.
