My 92 Cougar's heater is not working. All I get is cold even after running for 30 min. I bought a new climate control, but have not installed it yet, just incase its something else. I have heat through the hoses to the firewall, but after that nothing. Ofcourse air works fine. Throw at me what you think I will try it all.





Thanks In Advance

 

perhaps a bad heater core? any antifreeze smell in the car? dampness?

 

No smell of antifreeze in car. Doesn't seem damp.

 

Check vacuum lines to block(vacuum block/manifold,usually behind intake manifold under cowl/firewall area)and regulator. A possible leak to damper door will cause this to happen. Edited by: Lenny
