Weird electrical fault - washers and wipers on continuously
1993 900s Classic
My wife's car, she went out this evening in fog, turned on the wipers and the washers started too, both would not stop. She tried parking and turning the engine off to re-start to see if that would reset the system - would not start, no response to ignition and with the 'Check Engine' light on. I went out to meet her and the car started, no 'Check Engine' light but still with wipers and washers on continuously.
Removed the under-bonnet fuse No 5, stopped the screen wipers but the washers and headlamp wipers still run all the time.
Don't understand it at all - anyone got any ideas?
