The heater in my car went out i have no idea what went wrong. I checked the fuses and thats fine. A buddy told me to check my thermostat. Im looking a second opinion. Thanks

What exactly doesn't work? Blower? Blows cold air? Doesn't change positions between defrost, vent and floor?

First thing to check -- do your heater hoses get hot? They are on the passenger side of the engine compartment and should be too hot to touch when the engine is up to temp.

the a/c is really cold but the heater doesnt get hot. there is temp change though

F-body has a mechanical blend door actuator correct? My 96 mark VIII had a electric blend door actuator that broke and wouldn't allow the system to change from cool air to hot air,heater core was ok.
