    Greetings, the a/c in the sleeper of my '04 VNL630 does not blow cold. The fan works fine. The front a/c does a pretty good job with the curtains closed. Where should I begin to look for the problem. Thanks

    If you just started to use your A/C this year you may be a little low on freon, any place with a set of a/c gauges can hook up and get a press. reading on the system, just putting a can of freon in it will just be temp fix?

    When I had poor ac in the bunk but good up front I had a bad expansion valve on the bunk ac unit.

    It's either low on Freon, the bunk unit expansion valve is bad or both. If the Freon was full the cab would do a lot better than "pretty good with the curtains closed".
