oldstick,

Neither the front nor curbside patio lights on my 2008 3326 have a ground screw. The white wires are spliced with the splices that cut through the insulation of the wires, but no ground screws. There are no junction boxes behind the lights, either. Just a small cavity in the foam between the inner and outer skins. I have checked and re-done every ground connection that I have found so far with no success. I have pulled on the white wire splices, but none have come apart. I found an exterior junction box underneath the TM that has at least 10 splices, mostly butt crimps with light-gauge wires, and the whole mess is in an interior 1-gang old work box with a metal cover from an exterior junction box. I will have to replace that with a proper exterior flush-mount junction box. I'll keep looking. Thanks for your suggestions.
