I don't know if the problem is with my heater or if something is causing my engine to vent inside my Jimmy. I can have the heater turned off and the dial turned all the way over to it's coldest settings and hot air will continuously vent inside. Also, if i turn the AC on, it's nothing but hot air as well. I don't appear to have any problems with coolant or overheating. I'm not sure where to start looking to fix this problem.
