Is it possible to adjust the auto wiper sensor sensitivity, mine seems too sensitive and is left on the least sensitive setting permanently, yet this seems too sensitive. I rarely get a slow intermittant wipe, it tends to go to full wipe setting even when there is only a fine drizzle which means I end up turning the wipers off.

Sounds like there is a fault with the sensor.

Thats what I was thinking, car is due a service soon, have to get it checked out.

Does altering the position of the switch on top of the stalk make any difference?
