Hopped in the van this morning to notice a slow ticking like sound. Had a feel around and narrowed it down to the relays in the passenger footwell. It sounds like the wiper relay when on its lowest setting , so every 4/5 seconds it latches for aprox 2 seconds before releasing. Managed to pull the two lower relays out to try and narrow it down further, but it seems to be one of the relays above it. I can't see up there without a torch or without my legs outside the van and getting wet!
SO......
Relay issue?

Relay issue?
