Thanks BobC. I replaced a round plastic switch that the previous owner had noted on paper tApe “Flasher for temporary usel. So the result was no change. Will ask my local reliable service provider for the flasher part and see if different. I use Richards RV service in Greer SC. Currently on cross country trip.
I mostly agree with Bob C, except that if a bulb is out, you should see the rapid flashing when you activate the turn signal as well as the 4 way flasher. Looking at the lights outside should tell you if its a bulb or not.
