So my radio and instrumental cluster comes on by itself at night and drains the battery. The only way it doesn’t is if I have my wipers going when I shut the hummer off. Then it’s fine throughout the night. Any ideas?????

 

Carpetguy2013 could be a faulty front wiper motor pulse-board, +12V back feeds keeping those items powered-up, check out this post

To confirm, pull either the WS WPR Fuse (lower left side of dash) or the W/S WASH Fuse (engine compartment)

The pulse module may be repairable, but ​​​you might need a complete new wiper motor.

Hope this helps, keep us posted👍

 

Thank you so much! I’ll check that out. How will I know if it’s the motor or the pulse monitor?

 

The pulse-module is the electronic assembly part of the motor.

These videos will help.
