Over the Road AC Question

Yahoo Message Number: 18022
Today on a maintenance run, my cab OTR AC only produced 75 degree air.
I turned on the rear OTR fan in the bedroom and it produced 51 degree air.

Front AC selector was on, slide selector was on cold and later on recirculate.

I understood that the rear OTR AC would only work if the front AC were operating. That was the case on the switches, but why no cold air up front? I think both are run from the same compressor.

Anyone have ideas of what to look for to fix?

Thanks

Dean;

Your right about the compressor. Had ours replaced last year, is used by both front and bedroom a/c. The only thing that I can think of is the front cooling coil, under passenger side dash. I don't remember if there is a valve in there or not. Might also be the flap for the recirculating and outside air on the front unit. When you turn the switch, you should be able to hear the flap openning and closing, under the passenger side dash. Good luck.
