New to the maxima scene. I brought a 09 maxima S two months ago. I love the car but it has issues I cannot explain. 1st. When I 1st got the car, the passenger side front window would not work with the master switch. no biggie. I assumed bad contacts. but now its my door locks. lock/unlock buttons work fine. The locks just keep locking even when they are already locked. they lock repeatedly when the car is off/alarm active. car is on, driving etc. I also noticed that the beeper that beeps 4 times when you leave the car running and take the key out will sporadically have a very fast beep. (think ticking time bomb about to explode). I have looked for fuses/relay under both panels and come up empty. when the door lock it sounds like a relay click under the steering will where the tpms module i cant seem to find. . alsowhen it rains really bad the locks go haywire. the car is missing the drivers front fender guard. any advice helps as the local stealerships labor rate to diagnose is 110/hr

For what I saw, The tech remove all the underside of the driver side dash and the fuse box. Be sure to disconnect the battery. wait 5 minutes

Have you tried a different key fob? It may be as simple as a bad button on your fob, weak battery, etc. Also the Master Switch on the driver's side is a cheap replacement part and easy to do. I did my SV for about $40. Of course you may also check the passenger side switch as well.
