I have a 1994 Gulfstream Scenic Cruiser 34 foot DP. The switch to select heat or cool in dash unit is stuck in heat selection. I have looked under the dash and the cable goes to the drivers side or the vehicle and I can't trace it any further.
Where does this go and how can I fix the problem.
Thanks Bruce

Oldie but a goodie.
I can only give you generic information in that it goes to a water valve that directs hot water from the engine to the heating/ventilation box which is typically (in a gas engine) in the engine bay near the passenger footwell. In a DP then I am guessing that they route the water pipes up under the drivers seat where the valve will be in the line - they won't run a control wire back to the rear.
In 95% of cases, it's the cable that is sticking but it's possible that it may be the valve - either way they are cheap to replace IF you can get access to them - that's the big question as some are very easy and others are an absolute pig.
As the cable is a solid wire in a PTFE sleeve, they are not practical to repair and replacement is the only surefire way to get that smooth sliding action back.
