While my car is off the road I check everything every fortnight. This weeks checks were looking good when the sometimes erratic engine cooling fan cut in and out at the right temperatures, which sometimes it doesn't (I nearly had an overheat last year when stuck in traffic).
Unfortunately the windscreen washers have stopped working. Not the fuse as the wipers still work, and I swapped motors to no avail. Looks like the switch. Has anyone had any luck at cleaning these up in situ or is this usually fatal, requiring replacement of the whole switch set?
