So yesterday was the first good T-Top day in a long time. One problem, The incoming air through the vents passes over the heater core, gets stupidly hot, and then comes out of either the floor vent or the defrost depending on vacuum. This happens even when the ventilation system is turned off. And its speed related. It barely happens when going around town, but it gets uncomfortably hot when on the interstate. It burned my toes when I went to hit the brakes when cruising 70MPH.
What can I do about this? I don't have a vacuum reservoir or that other vacuum box that resides under the passenger side fender. The vacuum line for the vent system is simply T'd off of the line that supplies the EGR control valve.
