The 2005 Cavalier could have a fuel leak. Have the entire fuel system checked, as a fuel leak can cause a dangerous fire.
Thermostate stuck closed or low on anti-freeze or pluged heater core or bad water pump or the the A.C to heat deverter valve (if equipt) not operating correctly
Have your ball joints checked out.
it could be a few things, but id check the thermostat as its probly stuck open, or your heater core could be bad but that will cause a water leak in your car and its a pain to change. or you can check your heater hoses for sludge.. because 50/50 anti freeze tends to cause that
the first thing to check is the manifold air temperature sensor
No, a clogged heater core will not make it overheat. A leaking heater core will.
i was wondering whether the switch at the parking brake could affect this problem.
The 1989 Chevy Cavalier could be either a 2.0L 4-cylinder or a 2.8L V-6.
A broken rod is usually caused by a binding problem. The piston could be stuck or the rings may be damaged.
It could be that you need coolant or it's low.
Yes it could and so could a stuck open thermostat or a plugged heater core or a faulty temperature blend door actuator.
could be the oxygen sensor. that's what it was on mine.
If coolant level is correct - could be a defective sensor
If I could answer this question, then I wouldn't be asking it. Now would I?
with a LOT of fabrication it could be done. Maybe... I have seen a newer cavalier with a caddy northstar V8 in it. There is a video of it running on youtube.
You probably have a vacuum leak. Check intake manifold and throttle body gaskets as well as vacuum lines.
The fan relay could be bad or the fan motor could be bad.
heater core could be rusty and old or line to heater core could be plogged most likely old heater core
A blocked heater hose could cause a leak. A stopped up heater core could as well. Or the connector in the Windstar could be cracked.

Could you please tell me if a 1997 Chevy Venture has a heater control valve and if possible the location of the valve.
Heater core could be leaking
Is it water or coolant? If it's water, you probably have a leaky windshield seal. If it's coolant you could have a heater control valve leak.
Could be a problem with the thermostat housing or it's gasket, could be a problem with intake manifold gaskets, could be a problem with heater hoses or the fittings that screw into the manifold.
If the fan is not blowing, a fuse may be the cause. If there is just not warm air being blown by the fan, check your coolant level in your radiator. Low level of water and coolant will cause the heater to blow cooler air.
