I'm not sure if I'm in the right spot here but I'm gonna throw it out there , I have a 1989 Ram 1500 , was told yesterday I have no brake lights , checked fuses an bulbs all good , checked the brake light switch it fell apart in my hand . ...... I replaced the switch , now I have the brake light on the back of the cab ( which I've never had in the 3 years I've owned the truck ) but no brake lights in the tail end ......all other lights works ...checked wiring in back end it all looks ok .
