I noticed that the windshiled wipers would come on by it self, as time went on the dashboard lights and stereo would go off for about 4 seconds; later the horn would blow and the wipe fluid would squirt, then i would get a aweful shock when i touch the gear shifter. all these occur whenever i start the truck after sitting for more than 7 hours, then at any given time while driving with at least 4-5 times and ever increasing as mileage travelling.
