W900l blower motor quit!

Okay so sitting at the truck stop, started getting hot so, AC time right... Nope. The blower motor stopped on me. I figure that the resistor was bad before because I only had high speed. The blower was working last night when I shut it down.

I tested the switch with a new one and didn't change anything. I noticed that switch has power on three prongs until I flip the switch. Then all three lose power on all settings.

I checked fuses and relays and all's good.

The resistor has no power on any of the wires or prongs.

When I flip the speed switch off and on, I hear a click under the hood but I do not know where from.

Any ideas?

 

Guess it didn't stop on me, it just never came back on when I started the truck.

 

Okay there is power going to the resistor.

 

Thanks for the replies! I'm going to wait till I can get it back to the house Tuesday. I tried beating on the box but it was a no go.

In St. Louis I by chance turned out on and I felt air was happy till I turned on the AC and rolled up the windows.... It was air from the open wing window blowing on the vent. Sad day =(

I'll update what I find.

While taking the blower out I smacked the housing and it started working so I knew I was onto something. You can see what I found, I took it apart and cleaned it up, oiled and set it back in. I let it run while I cleaned up tools, etc. Jumped in and felt it and sadly there was hardly any air coming out of the vents =( So I turned it off and back on and it wouldn't restart. So I replaced it with a new blower motor and now that bad boy blows from places that I didn't even know there were vents!
