yeah, my ac will freeze me out. Heater dont make sence. I manuaIly turned blend door didnt help. I also back flushed from return hose throughwater pump. Only green coolant came out easy

 

The blend door I think fails in the cold position so you would have to physically hold it there. You want to backflush from the nipples coming out from the firewall. I would say you still have air in the system then

 

yeah, i took off motor and turned blend door. I can feel and hear it open all the way. Then air went from cold to warmish. I could even hear a change in the sound of the air flow. Any idea how to get the air out? Thanks

 

Park it nose up and even jacked up on the passenger side. You want the radiator fill the highest point. Start engine with heat on full hot. Get to running temp for several minutes.

This, however, has never worked for me. Mine never needs bleeding. All I do is dump coolant in, drive it around, and all is good.

 

ok, thanks

 

Same here all I do is squeeze the upper hose until no more coolant goes in. Drive around for the day and then top it off.

 

so when you squeeze upper hose it allows more coolant to fit? Sorry for the dumb ?

 

i just reved up to 2500 rpm and heat started getting hot!!!!! ?????????

 

Yep. As it's sucking it in like a vacuum clear up to the thermostat. Then when it opens you have to add more do that's why I said after driving around
Did you replace the water pump? That's what mine did when it was failing on my Durango

 

previous owner said he replaced 3 years ago
