I have a 92 Camaro RS V8. And I am having some issues with it. Most of my problems seem to be coming from the steering column itself. What could be causing my wipers not to delay. They just go at 1 speed at any settings. Some of the delays don't even turn on the wipers unless I have my left or right turn signal on; the only time they always stay on is if I have it in the low or high setting. Also for some reason my brights do not want to work. When I flick the lever to turn them on, they don't even make the clicking noise your suppose to get to trigger them. I was told that it could be the turn signal switch, what are your guy's opinion? Also sometimes randomly my Camaro does not want to start up; no crank or anything. I came to find out its the security because it will start when the security light goes away and won't when it stays on; now would that be the ignition cylinder? A buddy of mine told me to replace that along with a new key and that my problem should go away. And now for my trunk... The only way I can open it is with my key, when I press the switch it goes up and then it goes right back down. For some reason it doesn't unhatch it with the switch. What could be causing that? Thanks for the comments!
