check that the gate valve is operating properly on your heating system,
check that you have the propper amount of coolant and the propper mixture,
check the temperature of your thermostat and that it is working propperly,
To test your thermostat remove it from the vehicle and boil a pot of water on the stove, when the water is boiling drop the thermostat in and it should open, if it doesn't it is no good.
I would also recommend installling a195 degree thermostat if you live in a cooler climate.

I have a 2006 yukon and have had to replace the actuator in the rear heat/ac twice.  It moves a valve that closes the cold/hot ducts.  It is a cheap defective part/design.

Odds are your heater core isn't working or plugged. Check your passenger floorboard for water, and replace the heater core. If that doesn't fix it, get a coolant system flush.

My 2001 gmc sonama heater doesn't work ..only blows out cold air...what's wrong?


This no heat problem is one off two things, you may be low on coolant and its not flowing into heatercore or the actuator motor that controls the blend door is bad, the blend door is a door in the heater boxs that opens or closes to give you hot air or cold.

Check the magnetic clutch is engaged on front of a/c pump, have the motor running, a/c on and fan on high, if the centre hub is static the pump in not switched on, this can happen when the gas pressure gets low.

The heater still won't work after I changed the thermostat on my


Get a female garden hose adapter from the local hardware store. Disconnect the heater hose from behind the fan pulley and attach the hose connection. Disconnect the other heater hose behind the alternator, aim it towards the ground and flush water through the heater core. This worked on my truck.
