94 integra blower switch stoped working . But If I push the AC power button a couple of times its blows air from the vents. I turn off the key and restart the processes again doesn't work. I replace the climate control and the blower resistor and problem still the same. Any help will be appreciate. Joe

1. Disconnect and isolate the battery negative cable.
2. Open the glove box.
3. Flex both sides of the glove box bin inward near the top far enough for the rubber glove box stop bumpers to clear the sides of the glove box opening, then roll the glove box downward.
4. Reach through the glove box opening to access and disconnect the instrument panel wire harness connector for the blower motor resistor from the resistor connector receptacle (Blower Motor Resistor).
5. Reach through the glove box opening to access and disconnect the blower motor pigtail wire connector from the resistor connector receptacle.
6. Remove the two screws that secure the blower motor resistor to the evaporator housing.
7. Remove the blower motor resistor from the evaporator housing.

the hvac selector switch in the dash may be the problem.You need to remove the switch and look at the connector on the back of switch,see if there are any burnt wires at the connector or switch.It's all electronic and the switches have been known to burn out on this and other model.

HVAC control head problem or it is the air Temp Control Valve problem. THe control head is the one with the buttons and knobs and the control vavle is located on the HVAC carrier assembly underneath dashboard (two of them one on left and one on right in center). This is a job for someone who has knowledge of HVAC and electrical on a GM vehicle.

Have you tried smacking the blower motor? If it starts running after you hit it, replace it.
