blower motors bad check fuse bore replacing
Assuming the heater works fine, you have a short, probably in the AC compressor clutch.
the answer is air conditioner
check for coolant in system...radiator..next check for heater core leaking and verify if your thermostat is working(if it opens when engine is warmed up...hope this helps you..L
it is a heater. heat. it blows heat. warm air
Sounds like it might be a short in the wiring or a swich. Check all wiring and swiches. Hope this helps.
A more detailed explanation of the symptoms would have to be given in order for a determination to be made. As is, the question leaves us no indication of whether it's not blowing air period, or it it's blowing hot air, or what it's doing exactly.
It's obvious that you have problems with wiring. I would start from the heater/AC control panel.
The fan motor has a short...change it.
the air conditioner and heater are two separate things.(not connected) ;) it may have a fuse. or the it could just be bad.
your cabin filter might be dirty
Fuse, switch, speed resistor or motor.
Thermostat? or radiator? Greg
