What worked for us last summer, our first year with an EB auto control....
My wife kept turning down the temp to 50 degrees or the lowest setting when she first got it, so it would cool down faster....
All this does is put the system to full recirulate, of all the hot cabin air, than the compressor would freeze up and even shut down until it thawed out....
Went to the dealer a couple of times, and finaly got this answer, leave the temp at 68 or 70 all the time! She now does this and it greatly improved the first part of the trip with faster cooling down temps, it does seem to work....
