My WJ's heater doesn't seem to turn completely off; that is, it seems to leak heat when everything is turned off. The blend door seems to work fine. It directs heat where it's supposed to and the blower works fine. The A/C doesn't work because of a leak, if recharged it works for about a week.

Is there a door that seals incoming air? A/C cars don't have a fresh air bypass and with everything off, heat drifts out the floor vents making me sweat. I haven't found a diagram that shows the internal layout of the working parts so I'm not sure where to start looking. Anyone know what's going on?
