Also, a common failure mode for this valve is when the lever is in the
closed position but it still lets enough hot water thru to produce hot
air.  Of course you generally notice this only in the summer.  The only
long term solution is to buy and install a new valve.  Used ones from a
junk yard often have the same problem.
  I think that you can access the hose from inside the van.  Try
pinching one of them shut with vise grips with padded jaws to see if the
heat goes away..
