I have a 2003 Trailblazer LT and I am having problems with the windshield wipers. Sometimes when it rains heavily my wipers will remain on even after I turn them off. They will not turn off unless I turn the key off or for a few minutes after the rain lets up. I saw a recall bulletin 04V046000 that described the symptons I am having but after calling 2 dealerships and Chevrolet I have been told that my VIN number does not match the vehicles covered. I saw somehting on another site that the recall involves putting a plastic patch over a hole in the plastic windshield wiper housing because rain leaks in and gets the circuit board wet. Does anyone know anything about this? I will fix it myself if I can just find out where to put the patch. Any help would be appreciated.
