Air conditioner fan not operating

We are on our 1st trip we hit the grand canyon, and ZION and our staying our 1st knight with 30 amp hook up and I can't seem to get the ac unit to work. The fan hi or low doesn't blow any air and when on ac lo or hi it sounds like it is working but doesn't blow any air. suggestions ??

Does the fan run but move no air (it is noisy, so you will know if it is running)?

Or does the fan simply not run?

Check it with the switch in one of the fan positions, not one of the A/C positions, so the sound of the compressor does not confuse things.

the fan does not run in any position, the compressor runs in both A/C modes. I have a 2009 2916, the previous owner said he never used it

Thanks

All breakers are in the on position, I don't know of any other switches

I was wrong my 1st statement was not correct, now that it is quiet I can hear the fan motor activate with a low humming sound. still not blowing air

First check to make sure that no debris is jamming the fan blades.

Thanks everyone for your help, I took the inside cover off and the squirrel cage fan moves freely, as I understand it there is another fan on the roof so it looks like I'll wait till I get back home to check it out. Thanks again for everyone help, I'll let you know what the problem was

Hi Hammertime -- I'm curious what you found to be the root cause issue. I recently bought a new (to me) TM 2027, 2009 model. Previous owner had not used it for ~3 years. When I got it home to check out the camper appliances, my A/C had the same symptoms as yours; I could hear the compressor come on in the cool modes, but in the fan modes, I do not hear the fan try to come on ... and certainly there is no air moving. Thanks.
