my 93 intrepid doesn't seem so get much heat from the heater unless i leave the fan on at half-way and the car has been running for about 20 minutes if i turn the fan on full it blows hot air for only a few seconds then starts to blow cool air and i have to turn it back down
any ideas what might be the problem?
the thermostat was replaced about 8 months ago because it was giving me an error code that the engine was staying cold to long i forget which code that is but i replaced it then and i haven't had the cooling system flushed but i did have the rad out when i had to replace my crankshaft oil seal and i put almost 2 gallons of antifreeze back in, but i'll try replacing the thermostat again first if that don't help then maybe i'll have the system flushed
I trust you also put an appropriate amount of water in? (Pure ethylene glycol will gell and not flow through the rads in the cold)
Also, did you purge the air from the bleeder fitting at the engine rad hose connection?
hmm i used to always just open the vents to outside air and would get nice warm air comming in without even turning the heater on... course that was on my little truck dunno how the 1st gens are tho... but could try
