And thanks, I will search for the drier and try to find it
so I can change it also.
When I had an Endeavor it had an elect
fan for the condenser so if yours has
one make sure it is operating .
The dryer on that coach was up front
but on my 03 Windsor it is located above the differential
so it could be just about any place .
I had a very similar problem with my
air cond so I flushed the system with
a flushing product , replace the expansion valve and drier , that
fixed mine .
Good luck , keep us posted on how it goes
