Just noticed last night all my cab lights are out. The regular marker lights, front side and rear and still on, but my top lights (cab lights) are out. A few days before I noticed 2 of them were out, but thought the bulbs just went bad. Now they are all out. Where do I start.
take the driver's side kick panel off, the connection for them starts there. test for power with a test light. if you have power there, remove the 1st light on the left.test all the wires for power. you may have to go through each light, and recrimp, use liqiud electrical tape on all your repairs. replace the bulbs while everything is open, and put some die electric grease in where the bulb goes, to keep it from becomeing corroded. when you remove the screws for the lights, the gasket may have them stuck to the roof. some gental prying will get them broke loose
also check where the screws go into the roof these are the ground for these as well.the screws could be corroded and have a bad connection.use grease on these as well.
