Turn signals/hazzard issue

[jscraiderfan]

Trying to figure out if it's the flasher, the multi function switch, or something else. Sometimes i'll be going to make a turn i'll turn on the blinkers and at the first they'll work and then suddenly start flashing slowly or stop altogether, then suddenly start flashing again.. Sometimes if I actuate the switch they'll flash again sometimes once or twice and then stop again.. Then there are days they won't work at all and when the turn signals act up the hazzards don't work either. Kind of perplexed here I don't want to just throw parts at it. Anybody else ever have this issue?

It would be helpful if we knew the model year...

So when they do work... do all the bulbs illuminate when appropriate?

Also... any LED bulb conversion shenanigans going on with it?

It sounds to me like a loose connection or bad multifunction switch. Need to know if it's all or just some of the lights that mess up. Does it happen with both left and right turns? Or just one direction? Has any afyermarket trailer wiring been added to the truck?

Model year 2003 and when the turn signals mess up it's all of them hazards too I thought maybe it was a bulb issue because I was having issues with the right front turn signal bulb but I tried swapping them and that didn't fix it. It seems to be dependent on the weather too like when it's warm they mess up more often. No aftermarket trailer wiring.
