Blower fan on a/c quit blowing in front but still blows and blows cold air in back

If no air is coming out, the blower fan is not coming on. Find the blower fan, follow the wires back from the blower motor to a plug, unplug it, set it so the blower should be on, check for voltage across the plug. If there's about 12 volts, but the blower doesn't make any noise when you plug it back in, the motor has a problem (mine once quit like that because a moth got into it). If it buzzes, etc. the fan may be jammed.

If the front heater does not blow any air suspect a defective fan motor or resistor. You can try turning the blower on and banging the underside of the passenger dash to see if it begins working again. If it does, suspect a bad fan motor. If blowing only cold air, the most common problem is a low coolant level

Is your heater blower motor working on all speeds ? Are you get any air coming from the rear vents ?

Not sure which fan you mean. Engine cooling fan is different from heat/air blower fan.

Could be any one of several things, including a faulty blower motor, electronic controller, resistor, or relay.
Someone will need to check the blower motor for power and ground, then trace the wiring as needed.

check vacum to heater control switch

Sounds to me like the A/C clutch is no good and out of adjustment.You should goto your nerrest junkyard and get a used assembly take the clutch off then you learn how it comes off and install it on yours the save the pump for later use if needed. The clutch should only have a .010 air gap after install between th inner elctro magnet and the clutch plate it's self.

needs blower motor or blower resistor if it blows on high then it is the resistor if not then it is blower motor

I have a 2000 - the rear air is just a blower - it's not hooked up to the actual AC - just blows the cold air from front to the back

i have the same problem, my rear a/c blows great very cold, the front a/c blows but it is not cold at all. I had the the a/c seviced and it was vacumed and correct ammount put back in, no problems, the front still blows but it is not cold, i have checked everything and the a/c guy said it might be the door not opening. any help? still not working
