Greetings from Winnipeg, Manitoba Canada.
We have a 2006 Surveyor travel trailer which we have had from new. The problem I am having this year is that my left turn signal is not working all the time. I have tried the bulb in the other outlet and it works fine. I have also taken the working bulb and tried it to no avail. The running lights work and previously if I were to wiggle the bulb around it would work but now that does not work either. I had noticed some rust build up in the bulb outlet but managed to file that off but there was no change. Not sure if this may just be a bulb outlet issue??
