So I recently installed an led third brake and cargo light. Upon powering the vehicle back up I found that the carco light, interior light, cabin lights, sterio and guages do not work. The dash lights, head lights, brake lights and running lights all work. The manual has nothing of any help on this problem. Ive checked all fuses and they are all good. Has anybody had this problem? How is it fixed?

 

Haven't heard of it. Disconnect the new and see if you get them back.
