    I have had the exact same thing happen to my 1999 cougar. The headlights wouldnt work and the dash lights. I ordered a headlight switch and that wasnt it either. If you found the problem i would greatly appreciate hearing it because I'm lost at this point

I have had the same problems recently and I checked the relays, headlight switch, and changed all 7.5 fuses but nothing has worked. The fog lights work but nothing else does. Can someone tell me the problem???

Take a 12 volt test light and test out your headlight switch because that could be bad

Naso228:

balkjr Check the 7.5 amp fuse thats under the dash labeled high beams and low beams. I like a idiot checked all the other fuses under the hood but neglected to check that one and it was blown. Once i replaced the fuse my headlights work fine but still no instrument lights. For whatever reason i was able to blow the fuse again by shorting out the dimmer switch so i checked it with a multimeter and it had voltage going in but none out. I unplugged the dimmer switch and looked into it and alias noticed a solder in the middle pin that had snapped off. Its proved trickier than i had expected to solder it back but i know for sure that it is the culprit because i was able to use a pin to reach in it and hold the solder point down to get connection and my instrument lights worked fine. You can look right into the switch and see the solder point thats broke if that seems to be the problem for you also it comes from the middle pin on the switch and solders straight to the board. Just look inside the switch is made fairly open.

My headlights on my 2000 Mercury Mountaineer don't work. It's not the fuse. What could it be?


Check to see if your high beams work, also play with the combination switch that controls the headlights, it is typical for it to wear out and cause these problems.

1994 silverado illumination on instrument panel doesn't work, parking lights and tail lights do not work but headlights and brakelights work fine. All fuses are good. Is this a bad dimmer switch?


No. Dash lights being out could be a bad headlight switch, since the dash lights are routed through the headlight switch, not the dimmer switch. Park and tail lights also controlled by the headlight switch.

The headlights wont come on. I've changed the fuse. park light work but not the headlights. now car wont turn over at all. tried jumping it & poping it. radio comes on & the inside light is...


Hi, Those have a fuse in the positive battery cable located in the middle of the cable about the center of the firewall on its route to the starter. I would check that fuse before proceeding. Also, those cables are known to go bad, My daughter had a 2000 cougar that kept draing the battery and lights wouldnt work right sometimes. Eventually it fried the alternator. After replacing the alternator and battery cable, it worked fine. Try the fuse first, If it is blown, I would recommend replacing the cable to cure the headlight problem. Mike
