Hi- I have a 95 Caravan that suddenly lost normal heating ability.
I was getting warm air on defrost but when I'd switch it to vent or floor- cool air.
Did a complete flush and fill, replaced thermostat and now the heat is only warm when I rev the engine in neutral or park.
Put in a new water pump and had great heat for about 15 minutes...then back to cool air again! Grrr!
We're ready to warm this van up by setting it on fire- any help or advice is appreciated.
Thanks! Laura
