heater on at idle and will not blow warm air. when moving it blows the warm air from the vents. what will cause this
good question
most of the time its because not enough air flow thru the condensor---clean rad &cond
why does ac blow warm air? why does ac blow warm air?
if the heater does not blow out warm air change the setting.
Low on coolant. Stuck open thermostat. Poor circulation (plugged heater core).
low freon, bad compressor, clogged lines, plugged condenser etc etc
Isn't a heater supposed to blow warm air?
Could be, low on coolant, stuck open thermostat, plugged up heater core, temp blend door malfunction,
Heatstrips could be on with ac
I don't think it blows warm air... but if your talking about the part thats stays outside it blows warm air thats in your home and the part inside "replaces" the warm air with cool air..
It could be the thermostat on the engine. If the engine does not warm up adequately the heater will never blow hot air.
