Either it has low coolant still, an air pocket or most likely the heater core is plugged and needs to be back flushed

SOURCE: 2006 Chevy Equinox a/c works great but no heat what so ever ?????

If the blower is blowing air just fine, but you cannot control the temperature, you need to listen to air coming from the vents while turning the temperature from hot to cold. If you do n ot hear any change in airflow, then you may a temperature door in the dash broken. this is becoming a common problem on the Equinox

SOURCE: 2001 chevy monte carlo is overheating when driving

If your engine cools down when moving fast, you either have a problem with your water pump or your electric fans that cool off your radiator and a/c condenser. This is controlled by a temperature switch, but these fans should kick on instantly when A/C is selected.

SOURCE: My 2005 Equinox is overheating. We have replaced

hi, im sorry to say but the problem could be more serious it could be that your head gasket has failed and needs replacing, the only thing you could try is drain all the coolant then make sure that if you have an air bleed screw on one of the pipes that this is open then just trickle the water into the coolant system doing this ensures you have no air locks.
Once the coolant system is full then give it a try and see if it over heats, you may find that its just an air lock thats causing the problem but if it still over heats then your going to need to get a compresion test done or a sniff test to check the coolant for signs of engine gasses from the cylinder.

Let me know how you get on or if you need further assistance ok

My 2006 chevy equinox has no heat changed thermostat bled the radiator system im getting a little bit of heat Then I get cold air then starts getting warm again then cold What could cause this?

Are you sure you bled all the air out of the cooling system? This is the symptom of trapped air. There should be little bleeder valves on the engine near the thermostat, they kind of look like front end grease fittings. Open them up while filling and have the front of the vehicle raised to help the air escape.

Did you replace the thermostat as well? That could be your problem. Also make sure your radiator and reservoir are full.

Why is my coolant overflowing when my 2006 Chevy equinox heats up?

thet moment stop your engine and grab top radiator hose, feel the heat then grab lower radiator hose they have to be hot same heat. Top hose very hot is radiator blockage, Or lower hose very hot thermostat damage ,for test thermostat tide whith a string or wire have one glass cold water and juck boiling water deep thermostat in and you have to see the opening if is not then you have to replace it. Don ever youse radiator flush with the thermostat on. Blown head gasket means continual air bubble when you remove radiator cap special white froth,check for loose or damage hose and heter leaks when cooling system is under pressure.check low and high rpm exhaust fumes.

2006 Chevy Equinox Heater not working

Could you be more specific on what was fixed? and i would start by checking your fuses, do you hear any sounds when turning all the knobs? sometimes you can hear the heater flaps moving around when adjusting temp, the fuse for the fan probably is blown.

03 civic heat doesn't work unless driving

no that is a water pump or a stuck thermostat. see when you are driving the coolant is going through the system which means the faster you go the faster the water pump goes and more pressure on the thermostat. you have a stuck thermostat

Heater does not blow hot air do i need to change thermostat and how do i do that it is a 2006 equinox

Hello: Before you replace the thermostat, check the temperature door (air mix door) actuator. Make sure it is working. It should be on the passenger side of the heater case under the dash. Make sure the linkage moves when you move temperature selector on dash from hot to cold.

No heat blowing from vents already replaced

I had a problem with that in January 2008, my thermostat was fine. I took my car in to the dealer and they said the hinge that opens and closes the hot/cold air inside the dash broke. They had to remove my entire dash and replace the part. Luckily I was under warranty and didn't have to pay but the repair would have cost $3000.

You have a circulation problem, heater core may have restriction that why heat only comes when you drive ,also you may have a thermostat that stuck in the open position. Good Luck
