I have a 91 New Yorker and started having an electrical issue this morning. The seatbelt light flashes and the power locks keep locking. Wondered if anyone knew what some of the causes may be. I had an issue with the wipers turning on sporadically a couple years ago. Tried a new switch and problem went away for awhile. Ended up putting a switch in after fuse to control that issue. Not sure if these issues are related. Any help would be greatly appreciated! Thanks
