Electrical issuse HELP NEEDED
HELP I have a 2010 v8 Lr4 with 195k miles on it. I am having an electrical issue I just cannot figure out. for starters I have removed the kickplates on both the driver's side and the passenger side I have redone all the connectors I could find and I have opened up every wiring harness connector. I cleaned each connector and put Di-electric grease in each one and found some corrosion but not a ton. here is what I am dealing with. the driver's side window controller is not functioning, however each individual window is working. the auto tilt on the mirrors works but the controls do not. the next issue is the driver seat is not working, however, the seat warmers do work and I can power each motor and they work but the controller is dead. then I have the radio not functioning. there is power to the amp under the passenger seat but the heads-up display will not turn on and the CD player will not turn on. the last thing I have is warning lights on the dash the lights are as follows TPMS problem none are reporting the brake wear indicator is states worn brake pads I replaced both sensors and pads but it still indicates a warning. the last thing is the biggest issue. the vehicle is in performance restrict mode cylinder 7 misfire. I replaced the plugs I cleaned up the injector wires installed di-electric grease on everything the problem went away for a day then came back in keeps going away and coming back. I don't know what to do at this point I also have redone all the grounds under the driver and passenger kick plates nothing seems to be working all fuses are good and read normally. Please help point me to a bad harness connector that I could be missing or bad ground that all these items tie into that I could be missing. This car is in very clean condition no rust and my daughter cannot afford another car.
