This solution is for the 3100/3400 engine.
Air in your cooling system. There is a vertical black pipe with a bleader screw on the top. This pipe feeds directly into your water pump. It feeds your heater core and circulates coolant to your throttle body. Start the car, loosen the bleader screw. Air should come out. Rev the engine occasionally to push more bubbles out of the system. Keep an eye on the coolant level in your overflow tank. Once you get the air blead out check your heater.
Air in the system is systematic of a faulty head gasket or leaking hose.

2000 malibu heat works intermittently car over heats but cools off realy fast

Thermostat potentially.
You could have a hole in a line allowing air into the system.
having the cooling system evacuated and then have the fluid forced back into the system should eliminate any air in the line. As long as there is not a hole in any of the lines.
Turning on the heat when the vehicle is overheating will cool it off, that only works for the short term.
Can you smell coolant inside the vehicle? Is the carpet wet? Both could indicate a heater core failure.
Last but not least a blown head gasket would result in the same problem.

Well you've lost power to one or two major circuits. Could be a problem with the key switch or a major fuse in the engine compartment.
I would check the fuses for power and find out which ones are dead then go from there.

Why does my 2000 malibu over heat i repcled thermostat .waterpump,fans. radiator does notleak plus cold air comes out when tempature gage is on heat we tried bleeding lines, also sounds like agurgling...

A lot of the time the core in the radiator are partly pluged. The radiator needs boiled out or replace the radiator. One other item that can cause problems is old hoses. The bottom hose could be collapasing under pressure and the radiator cap could be at the wrong pressure setting.

I have a 2000 Chevrolet Malibu. I turned the heat on today and it wouldn't blow air. I changed the resistor and still nothing. Could it be the switch itself?

or it could be the blower relay in the underhood fuse box. I'm assuming you changed the resister in the blower assembly ??

2000 Malibu - No Heat

Try flushing the heater core, it may have a restriction caused by scale build up.

Blower motor or resistor?

If it was the motor that went out then it would not blow at all. The resistor is the culprit that starts killing off speeds. It should be about $25 to $30 at an aftermarket store like autozone or advanced auto parts.
