308 GTB loss of intermediate wiper

hello all. Ive lost the intermediate wiper. the next click down on the stalk and the wipers work, the double speed switch also works. i cant find any reference to the intermittent circuit in the wiring diagram. is the problem lying in the relay board or is there a box of tricks hidden somewhere under the fascia?

thanks in advance.
Alan.

 

I had the same problem on mine, tho sometimes it worked. I think its the contacts in the stalk switch. The delay relay is common to the Fiat 124 and is right behind the clock and oil temp gauge.
good luck

 

There's a contact point on the motor that's being push open/close by a cam lobe on the shaft motor. The contact point tab usually breaks off if the problem is not in the stalk.

 

thanks fella's ill give it a go.
all the best...alan.
