What could be a problem I was driving thru snow in IA last week my right turn signal came on flashed extremely fast and just stayed on green arrow not flashing or anything just on then all my trailer lights turned off if I turn my hazmat lights on only left side flashing not the right. I know it must be a short somewhere in Trailer "rewired all of trailer this week new wire new connectors". But if I disconnect trailer from truck and turn hazmat lights on only front left, rear left, and rear right lights flash, trailer dont flash at all even after new wires. But if I switch my turn signal on Right it works fine Left signal as well, worked on truck and trailer. What could be the problem?
