The fan is not working.
you have a vac. leake or the oneway check valve is not working.....
Your heater coil is bad.
heat and a/c barley blowing in back?
Car not blowing air or heat
Could be either or, but also a switch, not to exclude wiring or connections.
If the AC control is always blowing hot air, the AC control head has failed.
Replace the heater core. It is leaking.
What do you mean by "has no heat"? No air blowing out, blowing out cold air when heater is on, blowing nothing at all? Heater not turning on? What specifically is happening?
