Got a 69' camaro, and the heater stays on 24 hours a day. It doesnt blow out very hard just a continous blow of extremely hot air out of the bottom vents. The **** on the heater control broke some time last year, so I had to get a srewdriver and push it up to turn it off.That worked, for a while now it just stays on. Under the hood there are some plugs that I think go to the heater, would those fix my problems. Help Thanks Jon
