Check fuse first then A/C blower motor relay and blower motor itself to make sure you are getting power to it.

How to trouble shoot heat/ a/c fan switch.


Will your blower fan kick on in the medium position by chance? Med/ med high..if it is a 4 position switch, does it operate in the number 3 position? If so it is probably your blower motor resistor. If not, I would test the blower motor itself. Since the compressor kicks on when you turn the fan on, I would think the switch is working.

Why would my air conditioning in my Mitsubishi eclipse cool on #1 setting but kick off on any other setting above #1?


When you say "kick off," do you mean that the fan shuts off, or that the compressor cuts off? (Unclear.)
If the fan is shutting off, check your fan control switch, blower resistor, and blower motor.
If the compressor is cutting off, check your refrigerant level, and the compressor cycling switch.

Nothing coming from the vents when you turn on the a/c, heater, or defroster


You can jumper the fan motor to make sure it runs and if it does then look at the switch or resistor. You can also remove the resistor and omh acrossed it to make sure that it hasn't blown the fuse on risistor.

When i turn on the ac no air blows throw


Go to the fuse block and check 15A fuse D which feeds power to the blower motor. Then check 10A fuse K which feeds power to the blower relay and the fan (blower) speed select relays. If the fuses check OK, the blower relay, the fan switch or the speed control relays may be defective. also, the fan speed resistor may be defective

04 Saturn vue compressor turns off when fan is set to 3 or 4


The problem is the blower motor speed control resistor, it is located near the blower motor in the housing. I exchanged mine and it works like a charm now.

The ac is on full at all times, even when you adjust the fan hight. someone sayed i need a a/c auto amplifier. but i can't find that part


Good Evening, If I am translating this properly your fan only works on the high setting? And the other settings do not change the speed? If this is correct respond back and I will help as much as possible.
