Hello, I have 2020 diesel colorado that just got back from having front end work done after a deer strike. Ever since, it's been having a slew of electrical issues. Losing power to entertainment module, dash, doors locking and unlocking themselves, backup camera either not working or always being on, nearly everything electrical is malfunctioning. Had it back to the dealership that did the work and they said they 'fixed' the issue, but it's still doing all the same things. Any ideas on what the issue might be? I thought loose wiring at first but thay shouldn't cause this many issues all at once unless they screwed something up major.
thanks in advance.
