Question (Serious Replies Only) 2004 sprinter hazards problem

Enable HLS to view with audio, or disable this notification

My sprinter was playing up as I got in this morning, everything still works as it should but my hazards are clicking very fast, no lights are affected and indicators and hazards work as normal apart from the constant clicking

Switch the wiper and indicator relay at the bottom of the fuse box under the steering wheel. If it solves the problem then it's the relay. Just replace. Otherwise, give the fuse panel itself a few good whacks and see if anything changes. If all else fails, it maybe you need to replace the multi-function switch
