Power Locks Stopped Working
 
2006 Hummer H3

Both Power Locks have stopped working. I can't open the tailgate. The windows both work fine. Suggestions?

You still using the OEM Crappy Azzed Battery Terminal connectors?

This happens when the battery voltage gets low or if the battery has been disconnected. The computer is programmed to turn off some of the electrical items when low voltage is detected. It usually starts with the windows and locks.

This would make the most sense. I often leave the car on for long periods of time. Should I replace the the terminals or the whole unit?

Start by checking with a multi-meter, check resting voltage on the battery, then check at the mega fuse compare look for a voltage drop at the fuse block. Post your results.

The OEM Battery Terminal Connectors are JUNK, Garbage, trash, and ALWAYS fail, just a matter of time. #1 mod to be dine to every H3/H3T. Replace with Stingers or your favorite brand. Search it out, here and on the web.
