It could be that the Heater control switch that controls the heat is not working.It could be that the Heater control switch that controls the heat is not working.

How's your engine coolant level? If you've got a water pump leaking coolant, your belt will squeak, as the pump will leak the coolant directly onto the belt. You'll see the spray pattern under the hood if it's been going on for a while.
Hi, sounds like your hi-lo switch has broken. The switch is mounted to the steering column and is actuated by a rod that runs down the column from the wand. The switch is held on by 5 small screws. I have pasted a picture of the switch below.
follow the top radiator hose from the radiator to the engine, the spout the hose hooks to on the engine is the thermostat housing, you unbolt it, pull the old thermostat out, clean the joining surface of the thermo housing and the engine block of debri (old gasket) install new thermostat making sure the spring mechanism on thermostat is installed towards the engine, put the new gasket in place and reinstall the thermostat housing.
Well, that can be a ton of things. Usually it means: A. its not getting enough air, or any air. B. Its not getting enough gas. It could be a problem with the Mass flow Sensor- which can be cleaned or replaced-, or maybe a bad fuel pump or bad fuel lines or something. Either way the problem sounds like it just can't run because it can't get enough gas.
