There are three setups.
#1, most basic; off, int (not variable), on, faster
#2, on most higher spec cars, off, int (variable by the twiddly thing on the stalk, has dashes or something by the line), on, faster.
#3, highest spec (etacs cars) off, int (says auto by the little line on the stalk) on, faster.
I think the intermittant relay is built into the stalks on the pcb(green colour on the variable and basic stalks) the pcb is way different and the relay is on the firewall for the etacs stalks.
Its -7 outside, and i'm typing this in bed so i'll not dig the stalks out to take pictures of tonight.
If its running all the time,and the adjustment has no effect. Pull the stalks off the column and drop an ohmeter across the two small wires coming out of the metal tube the stalk moulding fits onto (trace these back to the pcb) if the switch is working the resistance should change and give a clear escalation from one end to the other, if it doesnt then the twiddly switch is toast. You can change the one stalk but watch for the ball bearing in the end that gives the detent for the washer pump running.
Hope this helps
