Heater don't works
Hi
I have a problem. My heater don't work sience i bought my Chevelle.
The Ventilation engine works. But the air is not warm.
I checked the inlet and oulet of the heating hoses. They are both equally warm. But not hot.
What do you think is my problem? Thermostat or heater valve?
Thanks a lot!

Welcome to the site. I am having a similar issue myself with no heat. Unfortunately my fan doesn't work as well. Good thing summer is comming!

Was it sitting for awhile? My 73 had a huge mouse nest in it.

X2, plus I had a nest in the cowl where the wiper mechanisms are.
The H-Valve & Thermostat are inexpensive & they're worth replacing anyway every once in a while. Check your antifreeze level & check it's potency- you may want to flush the system if it's old.

Re: Heater don't works
Here in the Northland, whenever a car isn't putting out heat (and, the blower is working), the first item of suspect is the thermostat. That's assuming the coolant level is where it should be. As I understand it, the Heat/Water Valve should always be open unless you switch the Temp Control to A/C...which then closes it to prevent coolant from flowing to your heater core. As Mali states, both are easy and inexpensive to replace...and a good time to backflush the coolant through your heater core. Actually, it's very easy to test the Heat Valve by simply pulling a vacuum through the hose and determining that the insides move freely.

Re: Heater don't works
Could be the cable for the heater door is not hooked up. How does the lever move? If with no resistance maybe its broken.

Re: Heater don't works
On my car the cable was not attached to the heater door. Once I fixed that (and lubed and streightened the cable), presto, heat. Well, reasonable heat, not toasty.
