A/C stopped suddenly

[tikitom]

While driving my 2001 Monaco Dynasty the a/c blower stopped blowing. We have no fan speed at all. A/C fuse does not appear to be blown. Any suggestions?

Most likely would be the blower motor resister, that is usually the problem. Could also be the fan speed control switch or the blower motor itself.

Sorry but he eliminated the resistor already...

What chassis? I ask because I have a workhorse and can provide specific info on that.

On my workhorse the blower is on the far right, under the dash, where my co-pilot/navigator (if I had one) can kick it.. and knock the ground lead off the motor.

I also had that kind of problem with mine, all fuses checked good epically the one marked for the job.. With a bit of help from another Forum member, OEMY, my attention was directed to a terminal block, where the terminal for the HEVAC had nothign hooked to it (So much for that fuse) Further inspection found a wire labeled HEVAC hooked to a nearby terminal,, I traced that (using documents OMEY provided on his web page) to a circuit breaker... Fast trip to auto parts store.. COOL man COOL. (blowing out the vents).

To clarify, dash A/C? Or camper A/C?

Had similar problem in my camper.
Turned out to be bad 12v converter.
Mine would swing from 9.3vdc to 12.2vdc and back in one minute.
Once it swung below tolerance, thermostat stopped a/c.

It is a Roadmaster chassis. It is the dash A/C that has stopped working.

Sorry I did not update our dash AC issue. Turned out to be a loose wire on the back of the AC control knob on the dash.

Better late than never. Thanks for the update.
