If your blower still blows air just not hot then you are more then likely low on coolant.

The blower motor has nothing to do with the temperaure of the air as long as it blows it is fine the heater core and the coolant level are where you need to look first

best of luck and if there are any more details you can give please do the title gets cutoff and I hope this is what you are asking

I would think the OP has checked the coolant level. It could be a lot of things, blend door is stuck, blend door actuator gone bad, leaky hose, and the list goes on from there. You'll have to start poking around a little to rule things out.

Why does a/c only blow whil vehicle is in motion?

you have a problem with the heater/a/c controls there obviouly stuck on a/c you will need to strip out the control panel to see why the direction/vent , hot/cold , fan speed controls are not working , before doing this have you checked the fuses as there may be a seperate fuse for the control panel ,if this all checks out take to an a/c specialist as you dont want to mess around with a/c gasses etc

The heater in my 96 escort will not get hot

Check the heater fuses and rheostat solenoid for temp selector. Possibly new heater core needed. Also check cabin filter may need changing. also check fan is working in all speed modes.

Ac fuse keeps blowing

An OBD-II reader will give you the error fault code to direct you to the cause of the problem. Your owner's manual contains the fuse diagram and explains the circuits they control.
The check engine light alerts you to the fact that the on-board computer system is reporting a diagnostic trouble code; giving the vehicle owner or repair technician the status of the various vehicle sub-systems, when it is accessed.

I'm looking for the fuse that goes to me heater. the fan comes on but it blows cold air.

the fan priveds air circulation, not heat. If you have power to the fan, you're good in the fuse department.
As for no heat - did you check the coolant level?
Any check engine lights on?
Have you added anything to the radiator to prevent leakage? (If so the heater core could be clogged or other obstruction in the supply lines to/ from the engine cooling system.)
Best regards

Air condition stopped blowing

If its your blower motor (Pass. comp.) check the fuse eather inside the engine comp. or pass. comp. by using your owners manual (fuses & relays section) Varify it does not blow when the heater is on. If it still not blowing and you have pwr. to the motor. replace the motor.

The air/heater just stopped blowing. If you turn it up full blast a tiny little bit squeks out but that's it.

Look under the hood at the fuse/relay panel, lift the top off the panel and look inside the lid for the correct location for the a/c-heater fuse and relay. check the fuse if it is ok then replace relay and the problem should go away. Hope this will help you.

Heater not working it is blowing cold air at all times is there a

Heater blowing cold air until I get on the interstate, then it works; however, when I stop at lights it starts blowing cold air again. The temperature gauge will be in the middle but the car will still be cold until the car starts moving.

The heater only blows hot air sometimes

it sounds like a bad blend door motor.these are controlled electrically and not with a cable like older vehicles did.
