Those hazard buttons are defective, they had an issue with cold solder joints, and the little tiny resistors or whatever in there come loose(solder joint cracks barely noticable) which is why when ya push on the switch sometimes your lucky enough to make a connection to get your signals to work, if your lucky enough to notice which one and have very good soldering skills maybe you can fix it and put it back in. The signals circuit goes right through that hazard switches circuit board so it affects the signals, sometimes they work and sometimes they click like crazy etc....It was a recall/safety issue around 2001. The dealer should do it for ya at no cost.
