have you checked your fuse? If it won't blow out the air it could be your blower motor.
replace front heater corefront and rear have independent heater cores
somtimes a mouse moves into the blower motor and makes a nest ?
hi, did you faind an answer, i'm having the same problem, Cheers
Switch problem? Cables disconnected?
It could need freon. and you can do it most auto part stores carry it so does walmart
heater core could be rusty and old or line to heater core could be plogged most likely old heater core
Likely heater core. I had same problem with 1996 S-10 with 4.3L.
First find out if the blower works. To do this disconnect the hot wire from the blower and use a jumper wire from the positive of the battery and connect it to where that hot wire was. if it does not go;;; then check that the blower motor is grounded.
If it does not blow at all then that is a problem, but if it is when you first start it, the Caddy will not blow air on you until it is the selected temp.
heater will not blow on a 1996 ford contour
if the heater does not blow out warm air change the setting.
you would have to see a mechanic about that problem
Blocked heater core, faulty heater valve, disconnected connection to the heater valve.
the heater core could be clogged with rust or stop leak . or u don't have enough hot water flow through the heater core . under the hood on most cars on the heater hose is a off/ on valve to control the flow of hot water...anti-freeze...to the heater core.....R
A vacuum leak, or one of the doors is sticking/bad vacuum motor in the heater box.
Could be a bad thermostat.
Your problem sounds like the common blend door problem on the Ford Expeditions, and Ford Explorer. Check related link below
I have a 97 Buick Lesbre thermostat control temp blink every time I start my car and also blow cold air out what could be the problem?
Assuming you want it to blow hot, it could be low on coolant, a stuck open thermostat, a plugged heater core or a faulty temp blend door.
Could be the Climate Control Unit or Clogged heater core.
I have the same problem. Change your heater hoses, top and bottom !
Probably your thermostat
Your car could be low on antifreeze or your heater core could be clogged. With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!
there is a short in the wire connecting the blower motor or it could be your voltage regulator sending not a constant current to the blower.
