Sure can!!!

On your battery, you have a positive an negative(ground) terminal. The Postive terminal connects to your main fuse box and to your starter. The Negative connects directly to the fender wall.
Electricity will travel in a circular path in your car from positive to negative(or vice versa, I don't remember) Anyway, all electrical components on your car need proper grounding to prevent stray/intermittent voltage from messing with it. There are various grounding spots on your car to prevent this from happening. If one of the grounds should lose connection and stray/intermittent voltage should be introduced into an electrical component, it can cause it to act wacky. I would start by checking all these grounding spots to make sure that's not the problem. It happens from time to time, especially in high salt environments. (i.e. if your local road crews use salt to melt ice on the roads or along oceans)

I've attached a couple of files (pdf format) to show you where the grounds might be you should look at.

Good luck. If I'm wrong in any of my statements everyone, feel free to correct at your discretion.
