AMCJeepMJ Posted February 3, 2014 Share Posted February 3, 2014 Similar to other threads about no headlights- parking lights work, high beams work, headlight harness has been upgraded with a Putco from Amazon a year ago, but NO low beam headlights when knob is pulled out to headlight on position. Headlight switch sound like the culprit? I do not have a functioning multimeter. Link to comment Share on other sites More sharing options...
gogmorgo Posted February 3, 2014 Share Posted February 3, 2014 If you've got high beams, the headlight switch isn't your issue. I don't know how the putco harness is set up (I made my own) but if there are any fuses in it, check them first. Also try swapping the low and high beam relays to see if the low beam relay might be bad. Are you sure you don't just have two burnt out low beams? Other things to check would be the high/low beam dimmer switch, as well as wiring in between the headlight switch and the the headlights. A test light would be useful to see "where the power stops", which is more than likely where your problem lies. At the low beam relay socket you should have power from the headlight switch at pin 86 when the low beams are on, and constant power from the battery to pin 30. A multimeter or ohm meter would be useful for testing continuity to ground from the relay socket (pin 85). Link to comment Share on other sites More sharing options...
AMCJeepMJ Posted February 3, 2014 Author Share Posted February 3, 2014 I have a one year old steering column with all new parts such as the hi/lo dimmer switch from columnsgalore.com. The Putco harness is just under a year old and has two 30a relays that are four pins each. Headlights are Osram H4 Silverstars with Hella housings. For both the bulbs to go out at the exact same time it would be more than coincidence. Link to comment Share on other sites More sharing options...
AMCJeepMJ Posted February 3, 2014 Author Share Posted February 3, 2014 Ok, got them working- it WAS the headlight switch. Now to spend the next hour or so reassembling everything. Thanks for the assistance! Link to comment Share on other sites More sharing options...
gogmorgo Posted February 3, 2014 Share Posted February 3, 2014 The reason I said it wasn't the headlight switch is because the power is split between the lights after it goes through the switch... If the high beams worked, then what was wrong with the switch? Good to hear you got it working, though. Link to comment Share on other sites More sharing options...

AMCJeepMJ Posted February 3, 2014 Author Share Posted February 3, 2014 The switch did feel like it was grinding as the knob was pulled out and rattles now that its out. Well at any rate I'm glad its done. Link to comment Share on other sites More sharing options...
gogmorgo Posted February 4, 2014 Share Posted February 4, 2014 Huh. I guess chalk it up to electricity being black voodoo magic. :dunno: There's only one wire between the headlight switch and the beam selector switch... Oh well. At least it works.
