headlights not working... December 03, 2006, 01:08:06 PM Well guys, just as the title states, my headlights are not functional. All the bulbs are new, and the wiring seems to be in good shape. This is where it gets complicated though, when I pull the blinker lever forward for my high beams the lights come on then go back out when you release the lever. The headlight switch is fine however, being that it worked in my '87 cougar. Any ideas or thoughts are valued to me. Thanks! Quote Selected

It will even work with the headlight switch off.Well, that means my wiring must be bad, or there's a ground issue.I have checked the grounds on the core support and they look fine, so maybe there's a bad ground somwhere else. I wonder if there is any other electrical components that would cause this problem. also, It wouldn't hurt to try another switch. Quote Selected

headlights not working... Reply #5 – December 03, 2006, 11:38:01 PM Yeah, jcassidy is right, it can be the multifunction switch.If you have 12v on the red with yellow stripe wire at the M/F switch, then it's the M/F switch. If not it's back to the H/L switch. Quote Selected
headlights not working... Reply #6 – December 04, 2006, 12:07:37 AM just curious if he has a auto dimmer feature. An old 78 cougar of mine had it up in the grille and went bad. Its just a photodiode but still, it prevented my lights from coming on. Now that i think about it,, that wiring was a little rigged up to say the least. Quote Selected

Reply #7 – December 04, 2006, 08:45:31 AM Quoteill bet on the multi function switchProbably the dimmer switch "contact bar" melted the plastic carrier and isn't making contact anymore. I just pulled the plug and jumpered the red/yellow and red/black together. Only have low beams now, and flash-to-pass highs. I'll put in my "new" switch (and relays) someday.My previous post (several pages in...)http://www.foxtbirdcougarforums.com/showthread.php?t=6454 Quote Selected
