Hi guys! Need some help on my Liberty. I LOOOVE my 'lil blue jeep but I keep having problems with my headlights flickering off and on. Its really embarasing! There is no rhyme or reason why it does it either. My hubby has checked the fuses, relays, grounds and sockets. Changed the battery didn't help either. Is there a TSB or anything on this? Thanks!!!

I know your gonna hate me for saying it but sounds like possibly a bad headlight switch. Which means you'll probably have to get into the steering column to replace it. That would be where I'd start since you said he already checked grounds and relays and nothing turned up. Maybe someone else who has had the same problem will chime in with better advice/solution.

Yep most likely the multifuction switch.About $100 or so for the switch and about 5mins to change it out.Will need torx bit sockets,just remove the steering column covers(2-3 bolts) and one connect oand 2 bolts and the switch is out.

Well i would also have the alternator checked out and take it out of the car and have it done. I know autozone has those all in one machines that read everything. But with our self regulating alternators the only way to truely know is to test it outside of the jeep. But if the lights are going completely out and not just dimming then it is most likely the switch.

Actually the regulator for the alternator in a KJ is in the PCM(gas) or ECM(CRD) so the only way to test it is via the DRBIII or StarScan(depends on year).

Ah good to know thank you troy I just now that autozone diagnosed my ex's dimming lights as a weak spark because there machine showed the alternator as good. I ended up proving both him and her wrong in the end when the alternator went a week later. Made sure to even buy it at his counter.
