Dreadful wiper relay noise
 

I just started hearing a wiper relay noise behind the dashboard on the passenger side. It's a tick tick noise everytime the wipers move. I noticed it just after my '08 3.0si went through service fixing a creaky noise coming from the passenger side dash. Was it always there or did the dealer screw something up? I'm not sure but is there a fix?

Happened in 2/3 of my E36s. I thought it was normal, just more "hidden" away in our vehicles, thus causing the sound diffusion.
