I have a 2000 Jeep Cherokee. Everything on the jeep works great except the heat and air conditioning. It will blow on defrost and work great but when I set it to blow out of the vents, it won't do anything, it just stays on defrost. It gets hot and cold when its on but I would like for it to come out of the vents. If anybody can help me that would be great.

I had a similar issue with my '01. Check the vaccum line. Does your vehicle have cruise control? If so, does it work?

My 97 Cherokee did and it worked but my 2000 Cherokee does not have it.

Ok. There should be a vaccum reservior (mine was attached to my front bumper). Check that and see if the hose that runs to it is disconnected or dryrotted. If so, replace that and it should fix your problem.

There is a small motor that controls the diverter doors on the 2000.
It is plainly visible on the face of the AC/HEAT box. When you move the control on the dash, you should see the the little motor spin and the control arm move. 2 mins, Easy swap. . . .IF . . . that is the problem.
