Re item 2, tailgate washer
Check if the washer motor up at the reservoir is attempting to pump. You can even pull a hose off and see if it's pumping. If not then start by doing electrical fault tracing as it could be the motor, relay or stalk switch. More than likely the problem is at the rear and it's a stuck/plugged check valve. The little diaphragm inside fails and can plug the port, also dirt from the reservoir. The check valve can be found by reaching up inside the right D pillar through the taillight access panel. The washer hose runs low along the right side and over the wheel well to the taillight area then into a right angled check valve before heading up to the tailgate connector. You may need to pull down the hose a bit to find the check valve. You can disconnect the check valve inlet to see if fluid will now come out, and if that works then try it with just the outlet removed. The plastic check valve at the rear is L shaped, while the one up front in the hood is T shaped. The L shaped ones are not common in the aftermarket, but the T shaped ones are. You can use a T shaped one at the rear by closing off one of the outlets, I usually just melt the end with a soldering iron. Double check for leakage before buttoning things up. The nozzles at the rear rarely plug in my experience. The slit in the nozzle makes it difficult to clean from that side, so perhaps try compressed air from outside with the check valve disconnected then inside into the hose before resorting to try carefully removing the nozzle.
