Fixed my central lock/hazard button.

Some condensation from a large iced tea dripped into the switch buttons and apparently re-activated an age old soda spill.

Turned into goo and stuck three buttons down and/or together.

Symptoms:

Doors locking and unlocking on their own, press hazard button and no hazard but the door locks operated instead.

I was sure the liquid got in and shorted the ckt so I went to remove and was expecting a soldering job was in my near future.

One of the easiest fixes "of ever"

Took about five-eight minutes and do to the luck of having a bottle of water near me and a utility knife I never left the driver seat!

Press a utility knife blade down the back and then there front (or two at once) and pry the sucker out.

The frame of the switch is only held on with tiny clips that can be released with the same utility blade.

Take apart all the plastic parts and clean them with soap and lots and lots of water. Almost always the defect is just that the buttons get stuck depressed. You can confirm by operating the buttons on the circuit board.

Wait until you hear what happened minutes before this.
