Hey guys there is a small grey box with wires coming off of it right behind my drivers front wheel. Its mounted by an open plastic clip that it snaps into. Not sure what it is, but when my battery is low, it clicks like crazy real loud. Trying to figure out what it is and if it has anything to do with the drain im having on my battery.

thanks for any help

 

It's probably your air suspension relay. It probably clicks like that because your air suspension is trying to kick on. They can get hot and get stuck open and run your air compressor when your truck is off if I recall correctly. If you disconnect it, you should get a "Service Air Suspension" message. You might try and disconnect it, charge your battery and let it sit overnight to see if that was what was draining your battery.

 

Thanks I'll give that a shot
