about a month ago a shop installed my NEX4100 on my 07 frontier CC and I left with my power door locks not fully functional. Keyless entry only unlocks driver side and master switch doesn't lock or unlock anything. Took the truck to a local AUTO Electric spot with very high reviews.
AUTO shop said my BCM is fried and I need it replaced. Luckily I have a friend who can give me wholesale prices through his business at no charge.
With that said, I am assuming the install of the NEX messed something up. I've already forked out about 200.00 just on getting to the root of my door lock issues and don't want to keep spending on diagnostics, How can I troubleshoot so this doesn't happen again?
I'd hate to buy a new BCM, install and the new BCM gets damaged.
Thanks for the help, it's greatly appreciated
