I have not had the strange one wipe syndrome. Just go to the dealer, and tell him (or show him) the delay when you press the washer switch before the wiper starts up. Then if he says that is normal (some will), tell him someone had the same problem and there was a new BCM calibration (actually, in TIS, this is called a TBC (truck body control module...don't ask me why), and they uploaded the new cal, and the wiper starts up immediately upon activating the washer switch.
It took me all of ten minutes. Go to the vehicle, connect the Tech 2, check for codes, download the current cals in all the modules, go back into the office, connect the Tech 2 to the computer, sign in to TIS, download cals from Tech 2 to computer, check which ones are updated, download the updated cals, then back to the H3 to download the new cals to the vehicle. The H3 is extremely fast when uploaded new cals.
A dealer will do all inside the bay, so they save the time walking to the parking lot and back a few times.
