ok guys I have a 2014 Z71 LT the door ajar light came on for drivers rear door I took it apart cleaned door latch (contact cleaner/dielectric grease lithium grease) put it all back together light went of but still have no control to dome light when door is opened and now the window on same door will not work and also passenger front window will not work I'm sure this is an electrical/switch/relay issue can anyone point me at a starting point dealer says it's needs a door latch and a new wiring harness in that door which I might would bite on but they didn't take it apart I'm assuming they diagnosed by computer? But now with the new issues I'm unsure any help would be greatly appreciated since truck is 4000 miles out of warranty and dealer wants 900 to fix just dome/latch issues
