Heater has suddenly quit working i can hear the compressor kicking in it is just not blowing

Blower not working suddenly is usually a blown fuse

Belief it or not your problem may be at one off your electric fans, also a possibility your a/c compressor coil shorted, so disconnect your a/c condenser fan and your a/c compressor check them for short and replace has needed, here is the logic every time you turn your heater on defrost it will cycle your a/c and it will blow your fuse, there is a circuit breaker on fuse box by left kick panel way up make sure it is in good condition push on it and you will feel it click if trigger, is not spring back it may be at fault to, replace it. good luck

Roger it sounds like the blower motor is not comming on. There is a resistor network located in the engine compartment on the passenger side mounted to the firewall, that controlls the blower motor. The connections may have corroted or the unit itself is bad. That was the first thing I had to relpace when I got my used 92 Dakota. There is also a 30 amp fuse in the fuse box under the dash board . If that is blown I would suspect the blower motor is seized up or just pulling too much power.

when you turn on the a/c does the compressor start turning?...find the compressor, and you will see its pulley turning all the time..but when it kicks in, you will see the inner part turn as well, you should hear it click when it goes on.
if it doesnt turn, could be low on refrigerant, or maybe your fuse is bown?

hope this helps

What you are most likely hearing is the compressor kicking on/off. The constant kicking could be a sign that there's insufficient refrigerant to keep the compressor running continuously without shutting on/off. Eventually, the compressor won't kick on at all, a safety feature designed to prevent doing damage to a compressor that's undercharged. Have the AC system checked.

Probably the blower motor resistor. Can you hear the compressor kicking on? If the fan won't blow at any speed, I'll bet it's the resistor.

Hope helps; keep in touch, and remember rated this help.

If you are absolutely confident the AC compressor is not kicking out on low pressure then it is the blend door actuator.

The blend door determines how much air blows through the heater core or evaporator.

The actuator can be purchased at dealer and maybe at a local part store.

You would have to measure the pressure to determine if it's pressurized correctly. The compressor won't run if it's low.
What happens when you push the a/c button? Can you hear/feel the compressor kick in? It seems like in most cases it's the compressor itself or the compressor clutch that goes. It's way too common in vw's...

Your heater controller or fan motor blower isn't functioning.

This is very vague. Is the blower motor working (can you hear blowing inside?), is it blowing but it's hot? Can you hear the compressor running (open your hood and listen if something is kicking on and off). AC is so complex. It could be as simple as a freon leak or as complex as a compressor, hose, accumulator etc.
