Has anyone had any success in locating or rebuilding the heater control valve on a model 501 heater from a P23? I mean the under dash unit. I have three and all leak. I took one apart(destroying it in the process) and found out that it seems that the rubber diaphragm around the plunger is dry rotted. Any help appreciated.
Do you have a Chrysler part number for that valve (books I have only go to 48)? Using Parts Voice or even the NAPA Online pro catalog lookup can do wonders if you have the original part number.
it ends with "Body", where the service manual continues with "accessories".
Index has nor heater nor defroster key words. Sorry! Go
