Broco hey i have an 88 bronco 2 it would not go in 4wheel drive and then the relay switch in the top of the dash quit clicking or workin any sugg

Check the wires going to the fuel pump relay for a ground with the ignition on. The reay requires a ground sent from the ecu to activate the relay and sent power to the fuel pump.

you can take a obd2 code scanner to have a check, it will tell you what problem cause the lights on.

Bad wiring contacts. Resecure all wiring and clean all contacts that you can get to in hope that you get it.

Well if he caused a short in the electrical system it could be the eec relay it is located on the passenger side under the hood on the fenderwell. Some are marked with what they do there can be 3-4 relays on it, the relays look like a small box with a connector at the bottom, and quite a few wires coming out. the one for the eec relay should be in the middle it was on my fathers 88 bronco 2. the fuel pump relay is the same thing, there cheap to buy and can find them at the parts store they are known for failure, just replace it..

The switch I believe is located in the cab, under the passenger side dash. Pull back the carpet under the glove box, it should be about a foot down from the top of carpet. It may be a little closer to the side kick panel. It will look like a fuse switch with two wires running to it. If I remember right, one wire is red the other blue. At least that's the location on the prior years Bronco II.

check the tan- lt green wire on the fuel relay that is located on the right fender, mine wasn't pushed in all the way, this wire shut down injectors and fuel pump, if you are looking for the shut off switch to reset the relay, it is on the passagers side floor board under the dash, gas two wires, orange and pink, I don't remember the color of the stripes, I removed this switch and wired them together without a problem

Check the linkage at the transfer case. There is also the switch to the light located near there. Check for worn out ujoints in the linkage this will keep it from fully

You don't need to remove the dash. Look under the dash where the switch is located. on the side of the switch you will see a small button to push in. While pushing in on the button pull the knob as though you were going to turn the lights on. At this time the stem should release from the switch. Undo the bezel and drop the switch down so you can see to unplug the wires. Replace wires to new switch and reverse the procedure to install. You don't need to push the button in when replacing the stem.

Check to see if you are getting power through your switch on your dash. I also suspect your shift motor but it is a lot easier to check it with a test light.
