Is there a shut-off valve for the rear heater coolant? If there is, can someone direct me to the thing?

Bill,
If it is the same as the one on a windstar, there is, and it is located under the vehicle/driver's side in front of the rear wheel. It is vacuum controlled.



I don't know what your issues are, but this thread may shed some light on it.

Thanks Poppy;
I have no idea whether the systems are the same but you have given me a good place to start.
The owners manual I found on line is missing the pages that deal with the rear heat system.
