My heater recently stopped blowing out hot air, stills blows air.

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.

Check and replace the blower motor speed control resistor.
