I've had my Riv in the shop off and on for the past two months with an AC
problem.  The climate control goes over to "economy" mode instead of
"auto".  We replaced the low pressure switch, and it ran for a week then
cut out again. When the mechanic clears the codes on the computer it will
run non-stop at the garage, but when I go about 10 miles it cuts out
again. I also have a problem with the digital dashboard cutting out--could
these problems be related?  Any ideas?
