If I am understanding you right the fan isn't blowing anything. this could be a couple of things it could be a blown fuse, a bad relay, a bad switch, a bad fan motor, or a bad wire. I would start with checking the fuses and relay if they are all good I would see if there is power to the motor when it is on if there is power it is ether a bad motor or bad resistors if your fan runs on high but nothing else it is probably the resistors if nothing works it is probably the motor. if there is no power at the motor when there should be I would check for power at the switch if there is power going into the switch but no power coming out of the switch the switch is probably bad. if there is no power going to the switch you may have a brake in a wire if there is power coming out from the switch but no power at the fan you may have a brake in a wire if you suspect a brake in a wire you can test the resistance going throw the wire by setting a dvom to resistance and touching the positive lead to one end of a wire and the negative lead to the other end of the same wire high resistance bad wire no resistance good wire make sure there is no power going throw the wire when you test is though or it could throw off the test.

Nothing is hard if you have patience and some tools or maybe even a friend to help.
Does the air go cool when moving down the road?
Does the vent air blow?
The fans for these are the same.
It is located under the hood, passenger side, right up against the firewall. They usually come out from the front.
Locate the fan motor - disconnect the wires - jumper to the battery with some clip leads, see if the fan runs. If it does, then not the fan and probably a fuse which is on the drivers side underneath the hood. It could also be the switching mechanism at that point, that's why try the heat and vent to see if anything changes.
If not replace the motor.
Let me know if there are any more fact to relay.

If you have a late model GM car
and the system is controlled electronically the blend door actuator becomes weak. When this situation occurs it will not move the air direction door inside of the heater/air conditioner plenum. in your case not to the vents Replace the actuator with new and recheck the system. i hope this helps

replaced clutch, driver ac belts on 2000 montero sport a/c is still not blowing cold any ideas

recharge your system, it;s low on refrigerat, there is not enough liquid going into the evap to help maintain cooling, hence the speed of the compressor. install gauges to check pressures at idle, if not to spec , recharge. if it's low you have a leak to repair. also make sure your AC condenser is clear. GOOD LUCK. RDJRP
