There are no predictable events leading up to this happening. the wipers will not come on at all. this will last from a few hours to a few days. washers will work. suspect controller board is defective. problem is so sporadic that i've not been able to get it to a dealer in time to show it to them before the problem fixed itself. has happened 4 or 5 times in last 2 years. *tr

I bought my 2007 silverado on july 27,2006 i began having electrical problems no more than two weeks later it went in the shop august 08,2006 for windshield wipers malfunctioning the dealer replaced the wiper module a couple months later october 10,2006 wipers were doing the same they again replaced the module and motors ok that's fixed,then my brakes were locking up and would drag when i would stop even at speeds of 5-10 mph and also stay locked after taking off from a stop and also was pulling left then right when brakes were applied they had to change the brake pads and resurface the rotors. march 26, 2007( i had my radio burn up a cd and lights in radio burn out they had to replace the stereo and the back lights on my stereo control buttons and other buttons on steering wheel burnt out they changed those. then my accessory outlet keeps burning out any time i plug anything in it blows a fuse, my speedometer cluster lights burnt out they had to replace that) june 28, 2007 back in the shop for a knocking noise in steering shaft they had to replace the steering shaft. may 05, 2008 steering wheel lights burnt out again they replaced the buttons again. then august 31,2008 my family and i were leaving town due to a mandatory evacuation and i was pulling my trailer when i took the ramp to get off the interstate i had no trouble stopping at the stop sign but when i went to cross into the median at no more than 5-10 mph i had no brakes and was pushed into oncoming traffic which resulted in a crash i bought new tires in july 2008 and you can tell that they are being torn up by the brakes i just got my truck back from the shop and noticed the rear brakes are locking up again and dragging through turns even with no brakes applied at 5-10 mph does this seem like an electrical problem. *tr

Windshield wipers and washer fluid come on without notice. there is no specific time of the day, number of miles driven in a day or any warnings this will happen. it also does not repeat itself on a regular basis. it has happened 4 times in less than a year on my truck. i have not carried it back to my dealer because it is so sporadic. *tr

2007 silverado new body style. upon taking delivery from the dealer i noticed a massive distortion in the windshield. dealer has ordered a new one to replace it. hopefully it's just an isolated problem.*ak
