One day my ac just stopped working. I've checked the fuses and relays they all are good. The heater works. It just wont blow air. The compresser clutch is NOT kicking in and i have no power to the ac switch and none of the lights work on the ac switches. I've replaced the freon and did the whole vaccum process. Please help.

sounds like the fan controller switch in the panel has gone nutty. I would take the car to the dealer and let them diagnose the issue, they are best when it comes to knowing your car the most and in diagnosing problems with them better than just a regular joe blow shop that works on everything and doesn't specialize in any particular issue.

First thing to check would be the fan speed resister, fan(blower-motor)relays, and possibly a bad ground. Start at switch on the dash and go to the relays and resister next.

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

SOURCE: My blinkers wont work but the hazards work. No fuses burnt out.

That would most likely be the switch itself. Fairly common

SOURCE: my brake lights do not work everything else does

If lights don't work, they either have no power, or no return earth. Therefore, remove a stoplamp globe and measure the voltage present in the globe socket. Next with a mutimeter, or battery powered light circuit, check that the globe sockets are in fact earthed to the frame.. If the earth is ok, and there is no power present, then you have a break in the wiring between the stoplamp switch and the rear of the vehicle.
