I have a 1996 express 1500 geneva conversion
I have a switch on the dash for rear fan speed but no temp,
I assume this is the same control as in the dash for front
The lines are hot going to the back of the van but it will only blow cold air out of the rear vents
Please heat my cold kids :)
I cannot figure this out

Matty322,
Sounds like your rear heater core may be plugged up though you stated "lines are hot going back" meaning both hoses.
Is your heater core hot to the touch? If not, flushing the rear heater core may allow passage of hot water through the core which would provide rear heat.
Good Luck!

I would also check for vacuum to the heater control. The blend door may not open.
