Just bought, 2000 Grand Cherokee Limited, 130+K. Everything seems to be in good order except the venting. It has the dual system with infra-red sensors. Passengers side works fine. Driver side always blows cold air. Somewhat of a foul smell, like stagnant moisture.
I pulled the fuse for the AC clutch, because it was always on. Driver side digital display of set temperature acts as I think it should. Blower seems to quit randomly, maybe linked to the smell, I did see smoke or steam puff from one vent on one occasion.
Any KNOWN issues with this system. I do not know where to begin to look. Need an idea before ripping into it. MSY-JSY
