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
hi, did you faind an answer, i'm having the same problem, Cheers
somtimes a mouse moves into the blower motor and makes a nest ?
Switch problem? Cables disconnected?
It could need freon. and you can do it most auto part stores carry it so does walmart
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.
Likely heater core. I had same problem with 1996 S-10 with 4.3L.
heater core could be rusty and old or line to heater core could be plogged most likely old heater core
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.
you would have to see a mechanic about that problem
