I have a 1999 Express 1500 conversion van. The dash heat and A/C work fine. But, the remote rear heater box blows cold air through the rear vents (on all dash heat settings). Is there some reason why hot radiator fluid does not reach the rear unit? Is there some switch that prevents it from flowing to the rear unit? If so, where is that switch located?
Thank you,
John

Let's start by going under the van when the engine is at operating temp and make sure both heater hoses going to it are getting too hot to hold?
