The flap to change air direction to heater core could be stuck and not moving. check motor that controls it or vacuum lines that could hold unto it. check also heater core valve.
it could be stuck also and not letting hot water into the core to heat it up.

tnx 4 using fixya,

SOURCE: 05 Chevy truck, heater quit

It is a common problem, the cause is a Temperature Control Actuator.

In other cases, the dealer could said Module was bad... estimated 450-500 to fix. Try with this homework solution:

1) Start truck
2) A/C comes out defrost - wait about 10 to 15 secs
3) A/C then starts coming out the floor vents for about 5 seconds
4) A/C then starts coming out the dash vents.
5) While the A/C is coming out the dash vents, turn A/C OFF (otherwise it cycles back to defrost for good).
6) Turn truck OFF

Restart truck. It WORKS!!!!!!!!!!! and it did not cost me anything!

Keep us updated.

Heatdoesn't work, A/C blows out warm air and defrosts blow out cold air


Right think the problem is the heater core is blocked with corrosion ,now remove the bottom hose from the rad and the heater hoses then flush every which way you can including through the heater core reversing direction then ,refit all the hoses fill with water only and see if heater works if so the remove the bottom hose again and drain ,then add a minium of 3 litres of antifreeze ,its a anti corrosion agent as well as antifreeze and without it the internal of the engine will corrode and the slurry will block the heater first then the radiator ,

Could be the control switch itself. Or possibly the actuator that moves the door from defrost to heater. With the heater on, try switching from defrost to heat and try to hear if you can hear anything in the dash operating.

Temperature gauge fluctuates and the heater blows cold air


Definitely check your fluid level in your radiator. Top it off all the way. I've seen that happen multiple times on cars that were low on anti-freeze. If that doesn't work try replacing your thermostat. It's cheap and the easiest place to start if topping off the fluid doesn't get you fixed up.

It sounds like you have a blend air door stuck. This is in the housing of the heater a/c blower unit under the passenger side of the dash. There is a motor on the top of the housing that could possibly be stuck or on working.
