The heater blows great heat while excellerating, but when you let off the gas, the air from the heater turns cool again

Test or replace the thermostat and check coolant level for a start

I already replaced the thermostat and the coolant level is ok.
Someone said that there's a little door that has to open to let the air through and maybe that's the problem. I don't know.
Thanks,

I have the same type of problem with my 98 Villager. If I hold the engine at 3000rpm the rear hearter works as well. Could our problem be air in the system? Would "bleeding cooling system" help?

I dusted off my Haynes Repair manual for 93-01 Villager.
Chapter 1-23 talks about refilling the system after
servicing the cooling system. It goes step-by-step
on bleeding the system.
It takes a little time but it worked!
Setting still in the driveway and I got hot air front
and back!
Grace,
