i would be drving and all of a sudden my power locks would go insane, and starting today with the truck off the vsm will be clicking non stop. so i picked peoples brain and came up it was either the vsm or the gem. but on the door locks the gem comands the vsm to actuate them but when you hit the remote the vsm comands them directly, whereas when you hit the door switch it goes throught eh gem then the vsm. gem = General Electrical Module
if this doesnt fix it onlt y thing left is the vsm which is onlly 150 buck the gem was the cheaper of the 2 at 111
