did you buy a brand new switch? or replace with another old one, i did the same thing on an old Chevy i had 2 switches, 1 would turn my headlights on but no dash, and the other would turn my dashlights on but no headlights, maybe just need to try another used switch. or by a new one.
Tske out the old ones by removing the screws. Unplug the headlight. Plug in the new headlight. Put it all back together.
no it will not
POSSIBLY A LOOSE GROUND WIRE AT LEAST THAT IS WHAT I AM LOOKING FOR ON MINE,GOOD LUCK! The most likely cause on the late 80's Bronco & Ranger for headlight problems is the failure of the Dimmer switch connection. I had to completely replace the connector & switch on my '88 Bronco II to resolve the problem.
There is the FULL SIZE BRONCO and then the Bronco II ( the Bronco II is smaller , eventually replaced by the Ford Explorer)
There are 4 little screws around headlight, remove then unplug and replace. Vdubwizard

No, the front end of 92 - 96 Broncos is completely different than 87 - 91 Broncos.
The PCM for the 89 Bronco is located on the firewall on the driver side. You can access it from inside the cab, behind the parking brake pedal.
behind the covers in the motor capartments there are bolts to remove the light cover there also is a round holister (wiring harness) that twists off witch allows you the change the bulbs.
