Teekass Posted July 5, 2007 Share Posted July 5, 2007 Click it between high and low beams like 50 times. The contacts in the switch get corroded and sometimes don't allow the current through. If they ever come on, the problem is most likely in the switch contacts (could be an intermittent relay, but my guess would be the contacts). If this doesn't work, can you hear (and feel) the high beam relay click when you select high beams? Don't confuse it with the low beam relay clicking. If the high beam relay is not clicking: 1 - Make sure you're getting +12v current on the 86 pole of the high beam relay when the high beams are selected. If no current, either the contacts in the high/low beam lever are corroded, or you have a break in the wire between the lever and the relay. 2 - Check the ground on the high beam relay. If all that checks out, swap the high and low beam relays (or replace the high beam relay with one you know works) and check the high beams again. If the relay does sound and feel like it's working: 1 - Make sure the 30 pole of the high beam relay has +12v. If no current, check the fuse on this wire, and check for a break in it between the fuse panel and the relay. 2 - Make sure you're getting +12v on the 87 pole when high beams are selected. If no current, replace the relay. If there is current there might be a break in the wire to the headlight high beams. Quote Link to comment Share on other sites More sharing options...
naviathan Posted July 5, 2007 Share Posted July 5, 2007 Who made that diagram??? At the least it isn't even labeled correctly. It's showing the low beam into the high beam and vise versa. First check to make sure you're getting 12V from the switch to the relay. Then check that you're getting your 12V feed from the 20A fuse to the relay and back out again (with power applied from switch of course). If all that checks out you have a bad bulb. If you're getting 12V from the switch and the fuse, but not out, you have a bad relay. If you're not getting 12V from the switch you have a bad switch. And as always, check all your fuses.

toughford86 Posted July 6, 2007 Author Share Posted July 6, 2007 thanks for that got to get another combination switch there is something seriously wrong with it when i turn every thing on the only contact that touches is the hi beam point Quote Link to comment Share on other sites More sharing options...
