The heater in my 95 G20 is suddenly working intermittently. For the last three days, I get cold air through the vents for the first 20 minutes of highway driving, followed by the heat suddenly kicking in. Then, when I corner around a sharp right hand turn, the air suddenly goes cold, and then heat resumes when I straighten up. Ideas before I head to the mechanic?
