Hi new member here thank you. Have a very nice low mileage 09 TL. Car has been awesome! Lost my ability to lock car with drivers door handle black knob. Had a code b1142 which I need to dig into. Related to master power window switch module. Have others had similar issues? Guess I need to check continuity on button first before changing possible master switch. Wiring from button goes to window switch module. Thanks and glad to have joined!
