2000 WJ / All brakes lights malfunctioning
Help! I cannot imagine all 3 bulbs blew at once, but frankly I have not yet looked at each bulb. To date I have changed the 15amp fuse in my interior panel although it was not visibly blown. Next, I replaced my brake pressure switch, still no glory. The original brake pressure switch seemed like the plunger was short-stroking, but replacing it still did not fix my problem. If it helps, when I engage my brake pedal, my lights do not black out completely. I still have the other filament staying lit, the one that lights when the headlights are on, in both rear light assemblies. One last detail, I do have a professionally installed trailer brake assist installed and one connector is on the pigtail of the brake pressure switch. This was put in two years ago. Suggestions?
