Hadn’t used wipers in months. Tried them last week and nothing. Funny… but had other fish to fry. Yesterday afternoon checked fuse and it was blown. Swapped in good fuse and when ignition on front and rear wipers turned on, and front and rear washers. Stalk wiggling did not fix. Pulled fuse.
Today I had a better look. Both wiper relays fine. Must be the switch. Steering wheel off and switch assembly pulled ( simple, just remove the electrical connectors and three screws. It’s pretty obvious).
Noticed that the contacts for the wiper wash function ( the pull or push in the stalk) were all together. There is a springy center contact that is moved by the stalk to select either front or rear wash function. Seems I had all on. I moved the stationary contacts back as much as they could move. They are held in place by plastic tabs moulded into assembly. The pic I took was after that. Pity I didn’t take a before pic. Near side contact not shown fully in pic, but same as the far side one
No idea how this happened. Hope it doesn’t happen again…
