Now for the fun part; you'll need to locate the relay that powers the lights. If you have the owners manual I'd start there. If not, the I'd call the dealer to find out where the relay panel is and which relay in the panel. It is possible the relay panel is under the hood, passenger side. It will be a black plastic rectangular box, usually mounted toward the top of the engine compartment. It should say either ' relay ' or ' fuse / relay ' on the lid. Push in the plastic release tabs on either side of the lid, pull up gently, and look on the inside of the lid - there may be a "map" printed or stickered there that will show you what is what. Now try tapping on the corresponding relay as your helper turns on the switch. If that doesn't work, then look for a set of numbers on the affected relay and see if any of the other relays have the same number - if so, then switch relays to see if that works. Also look at the pins or spades on that relay - if any are dirty or corroded, try cleaning them and test out the relay.
Hope this helps!

    The sensor on top of the dash is for auto headlights. The daytime lights are a different circuit.

1987 ford ranger turn signals keep blowing fuses. have changed flasher fuse and switch on column. just keeps blowing?

first thing i guess to understand what is going on here ,is a little back to basics on how turnsignals work , first item you have is power fuse then it's off to flasher module than it goes to the turnsignal switch on colum ,of course anywhere on it way to there the power could got to ground and cause the fuse to trip, now the power depending on Left or right selection , is directed to lights on both front and back of truck,thankfully rangers don't have em on the side) now any place in this pathway the wire could go to ground and blow the fuse, now to troubleshoot and narrow down the area that fault is located , (1) replace fuse with correct size and ck for proper fit in fusebox and start and operate truck for a few minutes DO not use turnsignals, ck fuse is it still good if so go to step 2 if not stop and ck wire conditions in steering colum and switch(2) start truck and try right hand turn signal only verify lights working ,Ok yes/no if not replace fuse and try left side same way, Ok yes /no if right or left side only blows fuses take ALL bulbS OUT of lights and try again , if fuse still blows then look for wire fault on that side of truck if fuse is still good then look carefull at light bulb sockets for rust and powered corrosion (ill bet an 87 has some ) you may need to replace bulb sockets , they do sell em in autoparts stores .

Both break lights went out at the same time. Think it may be the fuse #15 wondering what else it could be. And, how hard is it to change the fuse? Do I need to disconnect battery?

Check if hi mount brake light works. if so ck bulbs.if not, ck fuse/ switch If switch was bad, I dont think you could get it out of park. Dont disconnect battery.

When lights are on, rear lights(brake) go out when brake pedal is applied. Third brake light works normally all the time, and brake lights come on in day time though they are dim. Rear brake and running...

sounds to me you have a gounding problem with the lights in the back. ck the bulbs to see if they are in good shape no rust and such. than ck the wiring in the back and see if you find where they are getting the for the light at
