The most common cause is air pockets in the cooling system. The cooling system may be low on liquid coolant.

That "thing" is part of the compressor clutch. When it’s spinning the clutch is engaged, when it stops the compressor is off. If it’s constantly cycling, you probably don’t have enough freon in the system. But remember, however the gas escaped before, it will escape again, unless you fix the leak.

Hello I have a 96 chevy tahoe I replaced the heater core the thermostat & flushed the system I had heat when I finished but the next morning it was only blowing cold air could this be the water pump?


Chuck, having done this last year on my 99' Tahoe I will tell you to check to be sure you have filled the system and purged all the air out of it. Be sure to open the heater wide open (all the way into the red area) to make sure the heater valve is letting water into the heater core..You can park the truck with the nose higher than the rear and that will help purge the system of air also. Sometimes it take a while to get the system completely full of coolant.

2003 Chevy Tahoe Front AC blows cold air but rear does not blow cold air


Check control switches, power and grounds, and the 'blend door' operation. If you have a 'no heat' condition throughout the vehicle you should look to make sure the heater core is not plugged, and that the thermostat is operating properly, and that the coolant/antifreeze level is within spec.

I have a 2002 Chevy tracker. It's been running hot on the temp gage. So, I have changed the thermostat and replaced the radiator hose because of corrosion but it still overheats and when I turn on


If there is cold air coming out the heater than there is air in the system. After you replaced the thermostat did you run the engine at idle with the radiator cap off until the engine came up to operating temp? Doing this will purge the air from the system.

2004 Chevy Tahoe. Heater working only at higher speeds.


you have air trapped in the cooling system. A good indication is that one or both of your heater hoses going into the heater core are cold when they should be hot.
Park facing uphill, raise front of vehicle so radiator cap is higher than top of engine. (You want bubble to get to radiator and out the cap.)
Leave cap on but loose, so bubble can purge.
Turn heater on.
Fill radiator and reservoir with 50/50 mix of antifreeze.
Start engine and run at about 1500 roms until the engine warms up and thermostat opens.
You will know themostat opens when top radiator hose is hot indicating coolant is flowing.
Shut off engine.
Fill radiator and reservoir. Install cap.

please Rate as fixya if this works. good luck
