Heater doesn't blow hot air a idle, ether have to rev up the engine or
drive to get the heater to blow hot ait. The Engine Temp guage is
reading normal after warm up, (needle is sitting at mid point) engine
isn't overheating. the rear heater is experiencing the same problem.
could this be a thermostat problem, or heater core ?

gbmls,

There is a very specific procedure for bleeding air from the cooling
system. My sister has a 94 Quest and we looked it up in the Haynes
manual. It requires a piece of tubing to route excess coolant from a
bleed point back to the coolant reservoir. I would do this procedure
first if I were you.
