check the plug at the back of switch it may be loose
Had the same problem with my Grand Prix, ended up that the ignition switch had to be replaced. Hope this helps.
have you replaced the dimmer switch? if not that may be the problem. I had the same problem in reverse( brights worked but headlights didn't) water damaged the dimmer switch on the steering column once I replaced it all was good.
it may be your headlight switch, all mentioned circuits are routed through it
I had the same problem, and it turned out to be a short in the wiring. Mine had the Cruise Control located in the steering wheel and when I turned it off...the lights worked fine.
No, the XJ Cherokee does not have the same heater box as a WJ Grand Cherokee.
If the headlights flash on and off, there may be a problem with the bulbs or fuses. There may also be a problem with the battery connections or wiring.
I had a problem with my headlights going off, not the high beams. Replaced the rectangular silver can thingy at the fuse panel under the dash on the drivers side. I put a higher rated one in, which is a no no, but it solved the problem of the headlights going out.
blend door failure is a common problem on 97+ Jeep Cherokee
check the fuse
There's a TSB on this problem.
hi the dip headlight means that you have a problem with the headlights it is a common problem recognized by the factory.
(http://www.wjjeeps.com/lamps/headlamps.htm) AUTO HEADLIGHTS CYCLE ON AND OFF WHEN THE VEHICLE IS PARKED AND TURNED OFF (with headlamp switch in "Auto" mode) The problem is most prominent on 1999-2001 WJ's, but it could apply to the 2002-2004 WJ's. The problem could be in the switch. The switch is a multiplexed circuit, the resistance of the HEADLIGHT ON position is very close to the AUTO position; the switch has been updated to correct this problem.
