Headlights sometimes cut out on a 1993 Dodge Dakota pickup

Could the switch be at fault?

have you tried another headlight switch?another thing to check are the grounds and the headlight sockets.turn the headlights on and move wires around.you would be surprised at thing you do an old fashion wiggle test.i'm a 25+ year automotive diagnostic and smog tech.

relay coil may be a bit weak and is sharing power with the headlight relay. Try swapping the relay with the horn relay or another similar one that is non-essential to operation of the car. If that doesn't work, you may have a loose wire on the headlight switch or at the relay socket.

some times when the dimmer switch on the floor goes bad the headlights will cut out. Try replacing the dimmer switch and the headlights should come back on. My 84 dodge had that exact problem.

replace headlight switch, that will fix your problem.

There is a fuse you may have more then one fuse box look under the hood & under the dash. Most of the time Chrysler will just put a number next to the fuses. Go to your owners manual & see what number is your head light fuse. If you still can't find the right fuse take your test light & check both side of each fuse if one side lights up & one side does not replace it with the same size fuse.

The fuse panel box is to the right of the glove box with the glove box door opened or beneath the instrument panel (dashboard) on 1989-93 models. For 1994-96 Pick-ups, it is beneath the knee blocker panel.

For Headlights check Fuse 20Amp.

how about the headlight relays?

check to see if both headlights share a common power or ground.

Have your alternator checked...
