Three problems related to fog light switch have been reported for the 2008 Jeep Wrangler. The most recently reported issues are listed below.
Headlights will flash 4 times and then turn off. Sometimes I am able to drive it and sometimes not. I have brought to mechanic twice now for that issue. The first time they worked fine for him,even though I had to drive with just fog lights the night before. The second time he put in a new switch but found that wasn't the problem and the lights were working again. . I brought it home and again the lights didn't work. Upon research I have found that a lot of others complain about the same issue and have spent hundreds of dollars on parts it may be, only to continue to have the same problem. I have a vehicle that may or may not work properly and it is very concerning to whether or not the headlights will go out during driving. This is a safety concern and should be addressed immediately.
Headlights continue to go out. Daughter has to drive home with fog lights. Engine fan comes on and off. Took to Jeep they said it was a short and it worked for a month, same thing. After research it appears the tipm is bad, lots of complaints etc. Online regarding this issue. The lights have gone off while driving on highway, and city street and also after the car was parked at work all day. It is random. I have tapped on the tipm module and then turned on the lights and they work again for a day or two and then go out again. This has happened several times since December 2015, the last time was March 5, 2016.
While traveling at highway speed at night, headlights suddenly went out. They remain out for over 5 seconds, may come back on just to go out again. In other instances since started, headlight behavior will become suddenly erratic, one light will go out while other remains on, or both may go out. When this emergency condition occurs, high beams or fog lights must be activated to maintain visibility, and control of vehicle. Since first occurrence both bulbs have been changed but incidents continued to occur. Headlights are stock bulbs.
