If the switch is concealed in the door latch--(common problem) Spray door latch liberally with WD40 open and close door many times--then spray with silicone should solve problem If not in door latch- could be faulty light switch or wire grounding somewhere in door switch remove, replace and check wiring
do not use wd40 on break parts..it leaves a residue....use a break clean product
Try Windex & a soft cloth if that doesnt do it Try Pam cooking spray, soft cloth of that doesnt work Try WD40 & soft cloth if that doesnt work, replace the board.

You can use a silicone-based lubricant or a light machine oil as an alternative to WD40 for lubricating squeaky hinges.
WD 40 should not be used on a person.
A single can of WD40 is small enough that it does not require special storage, except that as an aerosol it should not be stored near a heat source such as a boiler or furnace.
use some WD40 and spray in to gear shift area http://www.autozone.com/servlet/UiBroker?UseCase=S001&UserAction=viewSimpleDiagInfo&Parameters=info wd40 would work, BUT wd40 attracts dirt like a magnet and problem will come back use a dry lubricant, the dirt dont stick to dry lubricant
if you spray the latch inside of your doors with wd40, this should take care of your problem. Over time dirt build up inside causing the signal not to be received by the sensor. hope this help.
Before soaking metal jewerlry in WD40 to remove adhesive, test on a small area. This will prevent you from ruining the piece if the WD40 removes or damages the finish.
