Sorry for not responding sooner. My Jeep was in the shop for well over a month, off & on. They finally replaced the brake light switch, and it has worked fine now for several months. I'm not certain where the switch is located, but as far as I know, the only brake light switch is mounted above the brake pedal, under the dash. They also replaced the main computer, and another relay of some kind, but those did not fix the problem. I hope with as many problems with cruise controls as I have seen on this site, that maybe Chrysler techs have identified the problem up channels, and maybe a service bulletin will be issued soon.

Curise control & climate control

Hi everyone, My 2002 Jeep climate control settings is not shifting air and got stuck blowing air to the windshield, only. Some of it seems to work as it turns the A/C on if knob is switched to the A/C position, but the controls wont shift air flow to any other direction. In addition, which could be related, the cruise control is not activating. it does turn on (cruise light) but pressing set or resume will not do anything.
could it be a burned fuse? - thanks

WE have a 2004 Jeep Grand Cherokee with similar problems:1) the AC works but it does not blow air where the knob is selected (i.e. if vent mode is selected, no air comes through, but the AC works) 2) The cruise control does not work. In reading your messages, you indicated you might have some more detail troubleshooting. Please advise. Do you want me to write directly to your email address?

I'm sorry. What I posted on page one was pretty much all I have. I think what I meant was for one of the guys in this forum was he/she could call me and I would walk them through the process I used to trouble shoot my system. To help point out or explain what they are looking at. There is another possibility with the Cruise Control. It is some switch or relay that you have to remove the Steering Wheel to get to it. I am not a Jeep mechanic I just do what I can with what I have.

Hope this helps, I had the exact same problem with my 2001 Grand Cherokee, ((fan position switch won't work (go from floor to dash to windshield, etc.)), and the cruise control won't engage. I'm told both are due to a vacuum line problem, ). I fixed mine by replacing 1/4" hose located directly under battery mounting pan. Takes a little work but might be worth it.
First remove battery. Then remove pan, you'll need a deep socket 10mm with extentions to get at one mounting nut. Remove two nuts holding cable to fuse/relay box attached to pan. Move pan out of way. The hose that's causing all the problems is about 6" long going to servo. Replaced hose ($.77) and it took care of both problems. Total job took about 1 hour. From what I have been reading this is the hose that's causing everyone problems.
