ftpiercecracker1 Posted October 13, 2013 Share Posted October 13, 2013 Low beams work fine, but the high beams after running for about 10 min will begin to cycle on and off. On for 6 sec, Off for 8 sec, On for 7 sec, Off for 7 sec, so on and so forth. Headlights are factory output, no fancy dancy HIDs or H4s. I am already pretty darn sure its a headlight switch issue, but before i go diving head first into my dash (again) i wanted to ask the local panel of experts. Ftpiercecracker.

cruiser54 Posted October 13, 2013 Share Posted October 13, 2013 Headlight switch is getting overheated and the circuit breaker inside it is tripping. Put an auxiliary headlight harness in your MJ and enjoy long-lived headlight switches and headlights that are about 40% brighter.

HOrnbrod Posted October 13, 2013 Share Posted October 13, 2013 Check the headlamp switch connector first. Probably a fried terminal. Common. Aftermarket replacements available. Link to comment Share on other sites More sharing options...

ftpiercecracker1 Posted October 13, 2013 Author Share Posted October 13, 2013 I would really like get a HD headlight harness, but there is a slight problem. . . Before i did the front clip swap, i had the plain jane factory clip with Silverstar Silva's HL (or whatever they are called) They pulled so much that not even my dims would stay on, in desperation i just N-word rigged a relay so that at least i would have use of my high beams, the wiring was ugly as all get out, but it worked perfectly until the day of the swap. I was kinda of hoping that with the factory headlights i wouldnt have to worry about it, i guess not. I really don't want to have to cut up this unmolested harness, but if i have to i will. Hornbrod, the last time i messed with the switch i did have a melted connector. Which i did my best to fix. I am afraid there is something deeper going on here and not just local to the HL switch. :( Link to comment Share on other sites More sharing options...
