My car barely blows warm air when the car is fully warmed up. does it need a new thermostat? Or what else can be the problem?

 

With the key ON, check to verifiy the cable actually moves the valve on the heater hose (in the engine compartment). Got a 4-cyl or V-6?

 

yes key was on. I was driving it and the temp gauge was about half way. it is a 4 cylinder. where is the heater hose located in the engine compartment?

Thanks

 

passenger side of the car. There will be two hoses that go into the firewall. One of the hoses will have a valve that is controlled by a cable.

 

Please also check the coolant level. If low you might want to bleed the system when filling it. Then denpending on how low it/was or is......find the leak.

And we are assuming the blower is turning at full speed, just no or not hot enough air coming out.
