I haven't been on here in a long time because I haven't had a problems. Whoopie! Now I do. My electric mirrors quit working. I have an '09 Surf Side 29A. I have the owners manual for the mirrors. I have determined that there is no power to the mirror switch or the heater switch which are tied together. It's supposed to have a 1.5 amp fuse in the mirror harness, but the wires from the switches disappear into a factory harness that is labeled (38128). I have checked every single fuse and none of them are blown and I can't find the 1.5 amp fuse. Does anybody have any ideas where National picked up the power supply to these mirrors? I'm thinking since the feed to the mirrors comes right out of a factory harness it's got to be fused somewhere, but all the fuses look good and everything else works fine. Any help or thoughts would be appreciated.

If the mirrors originally worked but with ignition switch on as in my coach, look for a NRV added fuse panel under/in the dash that supplies power to coach builder added hard ware such as the mirrors, radios ,etc..

Thanks, I'll try that in the morning. I checked every fuse under the dash for "body builder" add ons, same on the core support. Any fuses remotely associated with 'body' got checked and looked okay. If I could find the power source for the harness, I could back track it to the switch I think.

Many thanks to M&EM, problem solved. Only on an RV do you run into this stuff. The green/yellow tracer wire from the mirror switch (power) is connected to a light green wire that is part of harness #(38138). That green wire goes to a 4 way plug, then another 4 way plug, then a 6 way plug. On the opposite pin position to where the light green wire goes in, a bright green wire comes out of the plug and goes directly to an accessory fuse panel (just like E&EM said). At that fuse location, there was NO fuse installed. Interesting? Except a while back I remember finding a 15A fuse laying on the floor mat. I thought is was just a stray from somewhere because fuses just don't fall out, right? Well that's exactly what happened. I installed a new 15A fuse and the mirrors have power! Like I said, only in an RV. Have you ever seen a fuse fall out of anything else?
