You do not need to disconnect the battery when working on purely mechanical items. There is no "reset" for GM vehicles, they retain the last 300 ignition cycles power or no power.

I am going to assume you are still using the crappy OEM Battery Terminal Connectors? If so, cut them off and replace with a quality aftermarket set like Stingers or your favorite brand. Your driver door window and locks are a common failure when you disconnect the battery and can take care of themselves after several ignition cycles.

 

I'm surprised you said "crappy" instead of "crappy azzed" lmao
