PTT solenoid
On my 2012 ETEC the solenoid (for both up and down) failed under warranty, then once again. Think I applied 12v positive downstream of the solenoid which revealed it was the culprit. Heard a theory that although seemingly well potted where the wires exit out the top, failures were due to moisture. On the new solenoid I applied more liquid electrical tape around the wires and mounted it upside down with wires on the bottom. So far so good. Probably lasted longer than my first two.
