What can fail
Moisture can enter the driver's door module, causing corrosion and short circuits on the circuit board. This may cause power door locks and windows to work intermittently or stop working, and could cause overheating that melts module components, creating odor, smoke, or fire.
What the fix does
Dealers will test your driver's door module. If it works properly, a protective coating will be applied. If not, the module will be replaced. Both repairs are free.
