Turn Signal Buzzing '99 F350 - Pirate4x4.Com : 4x4 and Off-Road Forum

I tried this in Tow rigs and Trailers, but didnt have much response. Ok, here's the deal. With the key in the on position with the truck not running I have left turn that works fine, four ways that have a slight buzz, and the right turn just solidly buzzes. With the truck running I have the same thing other than the four ways don't buzz. I have googled the problem and think it is probably the multi function switch, but I would like to know for sure before I spend the cash. The reason that I am hesitant is that in the multiple similar cases state that they have a constant buzzing that goes away when they hit the brakes or turn the signals on. In my truck none of that is making a difference. When I turn the right turn signal on and the buzzing starts the indicator on the dash lights dimly and stays lit. What's your opinion? has anyone else experienced this? What's the fix? Oh, and I'm not low on blinker fluid.

I take it that you checked all the bulbs?

It sounds like you might have a bad ground if all your bulbs work.

Also what things have you done to your truck? If you tapped one of the parking light wires to feed somthing else like trailer lights or somthing else that may be your problem. I had the same thing happen in my f150 I bought The PO had tapped into the front parking light to run a set of cab lights which caused the turn signal not the function when the lights were on.
