You didn't mention your engine temp gage. If you have a bad thermostat
frozen in the "Open" position - the engine will run cold and the heaters
will barely put out any heat - and the rear heater will be the hotter of
the two because of it's proximity to the engine. If it's not the
thermostat - and the rear heater puts out good heat - then you have a
blockage or restriction somewhere in the forward heater system -
obviously. Bad heater valve, kinked control wire would be the biggest
suspect.

I recently took the power pack (engine and tranny) out of the vehicle to fix a tranny problem. Could there be air in the heater radiator? If yes, what’s the best way to get rid of it? Or do I need a new rad?
