i have a 94 camaro v6. For no reason whatsoever, the locks will lock/unlock themselves while im driving, in idle, the car is off, pretty much any time they feel like it. Also, i've been experiencing some headlight dimming, which i previously fixed by putting a high output alternator in. help!

 

Maybe a moisture or other issue with your keyless entry receiver or wiring (I assume you have keyless entry).
