This is really getting on my nerves, especially since it is like 10 degrees outside. I have gotten the heater core flushed, put in a new thermostat(180*), took out the chip so the fans wont come on so early, still it blows out cold air!!! Anybody have any other dieas what it could be?

Ummmm, i take it that water pump still working fine, no overheating. May have something to do with under the dash where the lil flap which's from cold to hold, may be stuck on cold. Thats all i can think of.

when my heat would not work i found out that i broke the line that goes from the button to the heater controll
maybe try that>!>!>

 

My heat wasn't working all day today in 28 degree weather....maybe that was because I took my motorcycle today. After that, who needs heat in the car, a 60 degree room feels hot after those kinda rides

Have you flushed your radiator lately? At least check it and make sure its not dirty. If the color is dark brownish instead of orange you will be out of heat.
