“Several months ago, I was at a fast food drive up window. I had my drivers side window down while paying for my food and receiving my food. It was down pouring and the inside of my door got pretty wet. I wiped off the rain as best as I could but everything was soaked. The very next day the drivers side door controls started to go haywire. The window button stopped working and my door locks only worked occasionally until they stopped working all together. My side mirrors can no longer be adjusted from the drivers seat. I have to get out of the vehicle and manually adjust both driver and passenger side mirrors. I'm not sure if there is a short in the wiring from the rain or just what is going on. I asked a parts dealer to see how much it would cost to replace the drivers side door controls module and he was of no help except to say its a recall part because of moisture. I've looked this up and I see there was a recall but my VIN isn't on the recall list.

“WHEN TURN THE CAR OFF AND REMOVE THE KEY FROM THE IGNITION, THERE ARE TWO SPEAKERS THAT CONTINUE TO MAKE STATIC NOISE, WHETHER I HAVE OPENED THE DOOR OR NOT. IF I BUMP OR HIT THE CENTER CONSOLE IT WILL MAKE THE SPEAKERS LOUDER OR TURN OFF. THE CHECK ENGINE LIGHT IS ON FOR MULTIPLE CODES, AND I HAVE WORN OUT SHOCKS. THE SHOCKS SHOULD MAKE ME FEEL AS IF I AM GLIDING, BUR I FEEL AND JERK TO EVERY BUMP.”

“WHETHER THE CAR IS TURNED ON, OR OFF WITH OR WITHOUT KEY IN THE IGNITION, IT HAS A SMALL SPEAKER OR TWEETER THAT STEADILY STAYS MAKING A FAINT BUZZ. THE CENTER CONSOLE IS VERY LOOSE, AND IF YOU PRESS OR KNOCK UP AGAINST THE RIGHT SIDE OR THE BACK SIDE, IT BECOMES LOUDER AND/OR QUIETER. THEN WHILE IN AUTO (2WD-4WD^OR4WDL) AND DRIVING, THE TRANSMISSIONS FEELS TO NOT SWITCH GEER AT THE RIGHT TIME, OR FROM DRIVE TO REVERSE AND BACK TO DRIVE IT JOLTS FORWARD OR BACK REALLY HARD.”
