why are my wipers not working properly?

yesterday, my left wiper stopped working. The right one worked fine until today. the right wiper is now stuck in the middle of the windshield. I can hear clicks when I try to use the washers as if there is elec. going to the motors. What could be wrong? I find it doubtful that both wiper moters failed within 36 hours of each other. About a week ago, my dome light would not turn off. I sprayed the  switches by the doors with wd40 and the light would still not turn off, i disconnected the fuse. My keyless entry no longer works and I can lock but not unlock the doors from the inside with the power locks. Can these issues be related??
