Maybe your heat selector knob thingy isn't working right. I've had it happen to me before.

Check your coolant level first... If its not at the right level, your heat wont work right.

coolant lv is good maybe is the thermostat ?

It's not the thermostat. However, the switch that opens the heater core to coolant may be malfunctioning.

I'll look in my shop manual for you.

the heat works likes this:

first you have to have sufficient coolant levels....ONLY way to check is the bleeder valve located on the head...water outlet pipe. could be full under the cap but still have air in the lines.

second, the thermostat needs to be working...if it is stuck open you will have little heat...if it is stuck closed...well you will overheat. However if yours is stuck open, it will still heat up so long as you are not driving.

Of course if one or both of those were a no go your temp gauge would let you know. (air in the system leads to temp gauge shooting up, and then going down when you increase rpms)

third there is a temp control knob. It connects to a temp valve, it is located in line on a water line going to the heater core. If there is a problem with the valve it could cause and increased amount of torque to be used to turn the knob leading to the knob breaking. Or the valve could be defective to where you can not adjust the temp.

Usually this is the result of water level. You will need to get the car to operating temperature while NOT driving the car. Turn the knob all the way to heat (this will allow hot coolant to flow into the heater core) then open the valve, any air will be expelled.

If that is good, then with the car still sitting still watch the temp gauge...even if the thermostat is stuck open it should go up ALMOST half way...UNLESS the air temp is very cold where you live...still it should rise...if not...let us know.

If it raises when sitting still but drops when you drive...thermostat stuck open.

But that only addresses the issue of the coolant flowing properly...you may still not have heat. So post back and let us know.

Sounds like bjcammerx has this one down cold in general.

However, since you took a direct hit from a tree on the climate control, something could be broken or broken loose in that unit.

If you have ever put any kind of "stop leak" in your radiator, your heater core is most likely clogged. That is very often the cause of no-heat issues.
