1999 Holiday Rambler Endeavor Dash A/C Blower INOP

[glamisorbust]

Hi everyone. I just got back from a 3,000 mile road trip in my 99 HR endeavor DP. Everything went well, but the dash a/c blower motor quit working on me. I spent 2 hours with a test light trying to figure out why it wouldn't work.

I had power to the blower motor, but it would not work. I figured maybe I had a bad ground, so I ran a separate ground wire and it now works again. But, it is stuck on high only. Move the fan controls up or down and it just stays on full blast.

It will turn off, but the blower speeds do not work. It's either on full blast or off. Anyone here have any ideas what part has failed here?

Thanks Wizard, i'm gonna dig into this soon.

most likely under the front hatch
attached someplace to the A/C -heater box
if not there its under the dash between the fan speed switch and the blower

So is the problem a blown fuse, or a blower resistor block? Where exactly would this part be on my coach?

Dead ON........Been there done that. Easy fix.

Sorry double post.

Check the fan speed switch, They have a rheostat wired into them and that is where you speed comes in.


Here is a link of the part you might need and part number.
