XXLMJ Posted December 3, 2010 Share Posted December 3, 2010 So i drive my 89 to work everyday 4.0, 5speed, 4x4. Has a H.O. swap done by the PO. And 2 times in a row about the time i get to work my headlights start tuning off then on then off then on. Not for sure what the problem is, i kinda looked at the fuses to make sure none were loose, but couldn't find a headlight fuse. Do they have relays? And could they be getting warm by the time i drive 30min to work? Or should i start checking connections under the hood? Quote Link to comment Share on other sites More sharing options...
Automan2164 Posted December 3, 2010 Share Posted December 3, 2010 There is a circuit breaker in the headlight switch. Sounds like yours is going out. All you have to do is replace the switch. Happened on a '91 XJ I had. Rob L. Quote Link to comment Share on other sites More sharing options...
jimmy21669 Posted December 3, 2010 Share Posted December 3, 2010 Did you wiggle the switch at all while they were on? That could be going too... Quote Link to comment Share on other sites More sharing options...

signalb Posted December 4, 2010 Share Posted December 4, 2010 Make sure you check your ground wire too. Quote Link to comment Share on other sites More sharing options...
vaquaro Posted December 4, 2010 Share Posted December 4, 2010 Had simular event , replaced H/L switch , happened again so started wiggling any connector I could find in the circuit . Finally found a loose wire at the steering column plug in for Hi/Lo switch operated by the turn signal stalk . :dunno: Worth a try before throwing cash at it :yes: Quote Link to comment Share on other sites More sharing options...
XXLMJ Posted January 7, 2011 Author Share Posted January 7, 2011 Well I finally got tired of blinking my lights a random people so i changed the headlight switch and that fixed the problem. Quote Link to comment Share on other sites More sharing options...
Automan2164 Posted January 8, 2011 Share Posted January 8, 2011 Its more fun like that. I just held back the brights when the circuit breaker would trip. Then, eventually, I had a headlight blow, and with just one it wasn't enough to trip the breaker... So I just drove around with one headlight until I sold it.
