Hi, it could be that your heater matrix is air locked or blocked, have you bled the system? try to bleed the system with the engine at idle, is the bottom of your raditor cold? it sounds like you have an air lock somewhere, hoppe this helps

I have a 2001 dodge stratus and the heater only blowed cold aire now we changed the thermostat and it blows warm air when idling but when driving still blows cold need some help please


where did you buy your thermostat? if you bought a fail-safe style thermostat it could have been no good before you even put it in. also is your tempeture gauge coming up to operating temp?? if it isnt your thermostat may be stuck in the open position allowing the coolant to circulate freely and not actually warm up. i would also check the lines going into the heater core. if one line is hot and the other line is cold than your heater core is probably in need of a flush or replacement.

It may be you heater matrix that may be faulty also check the thermostate by taking this out and put the tjerostate in hot water if it opens then it will be your heater matrix that is at fault.
