Another Evans Dash A/C Problem...

Have the Evans Dash A/C in my 2015 DS 4369, and just experienced my first problem, which follows my 4-month winter stay in Florida. I'm getting NO cool air on either AC or Max AC settings, with fan blowing normal at all it's settings. Began looking into it today and found the temperature coming from the vents to be 83 degrees, with inside coach temp being a bit less. After running for several minutes I looked at the receiver/drier and saw that it was sweating and quite cold...the temperature on it was 40 degrees. With this low reading can I rule out needing refrigerant? I'd like to think that I might be able to handle replacement of needed parts under the front hood, and would much appreciate advice as to what my problem most likely is and what part(s) are likely defective.

If the receiver dryer is cold it is plugged.

Are you sure the vacuum doors are opening to let cold air out through your vents tubes to doors and coming off the control, plastic tubes dry out.

"007"...thanks for the response and question. I've had little time to look seriously into my problem...hopefully, tomorrow. At this point I don't know that the doors are opening/closing properly. Will tomorrow check that and the vacuum lines for any broken, pinched, off. I'm assuming that all the vacuum lines are located under the front hood in close proximity of the system parts. I read the Evans' link you mentioned and have looked through the Evans Technical Manual. You likely saw that a previous post informed me that my receiver/drier (R/D) is plugged, based on my description of the temperature reading on the R/D of about 40 degrees and the bottom of the R/D being very cold and sweating. I gather that the R/D if good should NOT be cold?? I'll see tomorrow what I can come up with and report back. Thanks for the help. Larry
