We have a 99, and when the heater is turned off, air still leaks through. It's get's pretty annoying when you have to roll down the window cause there is still heat coming through the vents. Anyone have any ideas?

I had the same problem when I bought my used Jimmy. After 4 hours, it turned out to be a vacuum hose. The mechanic ran a new one and all worked well.
