Two problems related to headlight switch have been reported for the 2008 Jeep Wrangler. The most recently reported issues are listed below.
My Wrangler headlights stoped working one morning. Turn the headlight switch on for them to flicker on and off a few times over 5 seconds then they stay off all together. Took it to the dealership they scanned it told me it was showing these 4 codes. B162f-right low beam control circuit low b162c-left low beam control circuit high b162b-left low beam control circuit low b1630-right low beam control circuit high they checked over everything and said that it was a faulty tipm.
On 4 occasions, my horn and windshield wiper have spontaneously activated. On the most recent occurence, we were driving at night and the headlights turned off for several seconds. This happened at highway speed but luckily my wife was able to cycle the headlight switch and power returned to the headlights.
