07 SUT driver side windows wont roll up or down. Window motors work with external 12v power, switching the polarity to roll up and down. No visible damage to DDM. I have switched the DDM with one from a Suburban and the results were the same. All other windows roll up and down. Global up/down switch same result. Mirror motors work, locks work. Can hear a faint clicking sound with trying the back drivers window but no movement. Anybody have similar issues?
