I have a 1999 Suburban 107,000 miles. At first the daylight running light stopped working. When I turn on the light it works fine. Then soon after that hear all the clicking down under the steering column. I removed the relay the clicking stopped but the turn signal and hazard light do not work. While under the dash I noticed the air conditioner vent's servo that directs the air flow to the legs or face was moving by its self randomly. I think I have a electric short or interference but where?
Thanks in advance.

That's a little creepy. I think I'd be weirded out if I saw the vent controller moving back and forth by itself, for no good reason.
You gotta nip that gremlin in the bud quick, before it spreads to the rest of the vehicle.
I would agree with the short, but tracking them down, can be both difficult, and time consuming. It could also be the charging system.
If your alt is not putting enough back in, the vehicle is going to act up. I had a similar situation with a grand am. gauges would go nuts, doors would lock, and unlock while driving, and interior lights would come on and off. Replaced the alt, and it was fine.
