I was wondering what would cause the heat in a 02 sebring to work when your on the gas,at idle theres next to no heat....Anything???

 

clogged heater core, radiator. Bad vacum control on the heater controls. Maybe a bad water pump, but I doubt it. I would flush the heater core

 

sweet,i never have seen this before.Dont understand how the heat would work only when on the gas,if its at idle theres next to no heat.Really dont wanna bring to the garage because i know where thats gonna go.

 

I would have to go with Casper on this, those are the first places i would check.

 

When your on the gas the RPM goes higher and hence the water pump runs at a faster speed moving more water.

 

most likely will just need a good flushing out. anyone think the thermostat might be stuck open and its just taking a lot longer for the car to heat up at idle? or does it get cold rather soon after coming to a stop from a drive as well?

 

my intrepid used to do the same thing. check on top of thermostat housing there should be a bleeder vavle. open it and bleed the air out of system. if you get air coming out of it its a air lock. these new systems wont move water thru heater core if air is in the system

 

bleed air out of system and make sure your coolant level is correct. I have seen this problem before and found that if you are just a couple quarts low this will happen. In my cases its been with the 2.7 liter v-6
