Just to followup, I did order a new thermostat/control switch assembly and installed it the other day. The unit now seems to work on all the different cold settings. Hopefully, I will get at least a few years of service out of the thing. Fingers crossed. Thanks for all of the input and discussion.

Yes I replaced the thermostat and control switch. It comes as a single unit and cost about 25 dollars including shipping. I have the unit on setting 3 and it has been running about a week turning on and off. On setting 3 it runs about 25 percent of the time which is about what the unit did when new. About 36 to 38 degrees F on that setting with outside temps 70 to 80 F and van interior substantially warmer. The only difficulty was the install location in the rear upper corner requiring my arms to be about 6 inches longer than I have. The sensor part has a coating on it but the "brain" is a little metal box that does not appear sealed. Due to the interior location moisture will always be getting in there and causing rust and degradation. Just bad design is all. I ordered two more and put them in the repair kit.
