It appears that all of my lights are working except for the reverse/backup lights. They were working fine until I had the alarm system removed. Whenever they removed the components of the alarm my lights stopped working. The alarm was basic, sound and flashing lights(nothing fancy). Where should i start?
Reverse lights will not work on 1996 Ford Ranger
Start by looking at all the affected wiring from the removal of the alarm, see if you see any issues with the wiring. Next, get a wiring diagram and diagnose the reverse light circuit, you may just have a bad reverse light switch, and is it possible it was bad before but you just checked after removing the alarm?
