Why do i overheat?

Low coolant level, bad thermostat, bad water pump, dirty radiator on outside, radiator tubes clogged internally, etc.

Till u fix turn on heater full blast & open the windows. It will help keep the engine temps down so you can use it while getting repairs.

Why is it overheating unless I have the heater turned on full blast?

The heater acts as an additional mini radiator to cool down the coolant. Sounds like you may need a new radiator.

car has electronic issues
tow to an auto electrician or impala specific workshop

burnt out fan motor
faulty climate control wiring or sensor

My 2002 saturn sl1 is weakly blowing luke warm air out when i have my heat at its hottest setting and my fan at full blast.

the best way to find out if the problem is in the cabin or under the hood is to touch the heater hoses when the motor is at operating temperature. turn on the heat full blast and feel the hoses; if they are both almost too hot to touch then the problem is with your blend door or its control mechanism. if one is noticeably cooler than the other then you,ve got a clogged heater core. if they are both cool enough to touch then your motor is running too cool

Here water moving in the heater when I start my 99 ford ranger. Goes away when I drive a few blocks. Sometimes I have no heat also?

It's not uncommon fot it to take several fill ups to get all the air out of the cooling system and the heater is usually the main culprit. I always turn the heater on full blast when I refill a cooling system and run the engine long enough to make sure the coolant is circulating in the heater. This is your most likely culprit.Have you checked the coolant level in the overfow bucket? It should be at the full line on the side. If not, then top it up and replace the cap. Even if it is full replace the cap but leave it loose. Drive with the cap loose for a few days and the heater on full. Check the coolant level daily and top up as necessary. After a few days you should have continuous heat. Then you can tighten the overflow cap. Hope this helps.

99 sable 3.0ll Heater omly blows cold air.. radiator and heater core and thermostat replaced.,system flushed.

Here are a couple of things I would try.

Make sure your coolant level is at the full mark in the reservior, ( plastic tank)

Start your engine and let it run 6 to 8 minutes, so it reaches it's operating temperature.
With the engine still running, turn your heater on full blast. You should hear a light clicking noise from the thermostat opening up to cycle the coolant from the radiator. ( sometimes if a sealant is used, and it shouldn't be in most cases, when installing a thermostat excess sealant can prevent the thermostat from operating properly )
If you hear the click from the thermostat then you know that's working. then.......;

Turn the engine off, look back behind the engine at the firewall you should see 2 small hoses, about 1 inch in diameter. While the engine is still hot, carefully reach back and feel both hoses, both should be hot. If only 1 is hot then the coolant isn't circulation through the heater core and you could have blockage in your system.

Another good possibility is, the trap door that moves between the heater core duct, and the a/c evaporator duct is not moving back and forth like it should. To check this you will need to remove a few parts from the lower dash to gain access to inspect.

I hope this helps you.

Air/heat blower is not working unless it is on high.

The heater resistor is probably faulty, its located near the blower fan
