I am interested in finding out if there is a way to increase the wiper speed during intermittent delay operation on my 2002 C4S?  The dash reostat allows for very slow to slightly faster operation.  I believe that the fastest speed is about 6 seconds between swipes.  You then need to switch to low speed operation, which typically is too fast.  There is a significant time delay gap between these two modes.  Is this operating delay timing correct?  It would seem appropriate to have a greater wiper speed delay selection over the infinite reostat range.  Most cars advance from slow intermittent to almost low speed functionality in this mode.  If this operation is correct, is there any way to modify the controller to offer a broader wiper speed range?  I checked the relay and cleaned the contacts.  It appears to be functioning properly.
