An air conditioner blows out heat
Check the colant level, it may be low.
it wont blow heat itll blow cold air
is there heat to blow or does the blower not work chk thermostat or vacuumn at htr sw respectfully
No, not if it's on a heat setting. Most home thermostats have a "Fan" setting that will blow cold air if the attic is cold.
Yes, and it can also make your car to over heat
Sounds like it is low on coolant.
you need to replace your heater core
Air conditioning will expel heat to the outside when cooling. On the heat cycle the reverse is evident
The control for the heat on the dash has a control for the back seat and also has a setting that says something like "Rear Control". This allows the passengers in the back seat to control their heat independently via a temperature control in the back seat (on the back of the center console). So you could have the heat on in the front and the rear on "rear control" and if the passenger in the back has set their control to cold, it wold blow cold air in the back even though you have the heat on in the front.
Could be low on coolant.
It takes a few minutes of run time for the compressor to warm up the discharge gas, which is the heat source.
check your thermostat first
it may blow cold air due to the fact that the heat anticipator on your thermostat may be set to long. you can change useing your owners manual for your thermostat but you should have a service tech do it
You can not get heat from cold water, The engine has to run long enough to get the water in the engine HOT. That is were you get heat from HOT WATER-- Coolent
Most common problem is that the blend door is stuck or broken.
heat core. leak. thermostat. no antifreeze.
my 94 explorer wont blow heat
There is a divertor controller under the dash that controls between heat and cold. Sometime the wireing harness works loose.
heat works in back not in front front blows hot for a few mins then cold
the blown head gasket would make it over heat. but it wouldn't cause the heater to blow cold, it should actually blow hot if that is wat happened
your heat exchange actuator probably needs replaced.
Check coolant level in RADIATOR when cold When light is blinking turn on heat and see if you have any. If no heat good indication that thermostat is stuck in closed position and needs to be replaced
it has to heat up, just like water has to warm in the faucet.
by opposite temperatures-hot(heat) & cold(cool) rising & falling colliding
