Electrical problem 6 cyl Four Wheel Drive Automatic 130000 miles
My brake lights quit working a few days ago. All other lights on the truck work. The cruise control works. The bulbs have been tested, they work, the brake controller (aftermarket) has been tested, it works. The brake switch was replaced twice. After that, I diagnosed the leads into the switch. There is NO constant hot into the switch (I believe there should be - pink wire w/ blue(I think) tracer). There is no power coming into the switch at all. I believe dodge sends the brake switch HOT through a multi function switch. Is there a diagram available for this that can be posted? Can the multi function switch be tested? It is a $110 part so I do not want to replace without being sure. The Chilton manual wiring schematics are worthless and very incomplete.
In addition the wiring schematic from the multi function switch to the fog lights would be appreciated, those have not functioned for several years. The lead that grounds out when activated, does not fully ground out (minimal voltage remains).
Vehicle, more specifically that above is a 1999 Ram 2500 Diesel. It is a half year vehicle in that it uses a brake switch from a 2000 Ram.
