2013 ford fusion - no climate controls and more - all dead at same time
What is your question?
Check Engine light on, next day Engine over temperature light, mice had eaten through wires - fixed problem. 4 days later, blind spot, cross traffic warnings, park assist, parking brake, and passenger side windows don't work (I can live with) but no climate controls (nav, entertainment, phone all functional). Diagnostics test showed lots of 'codes' misfiring. I asked if it could still be a 'mice issue'..nest in the dash behind the control panel.. told 'probably not'. 4 hours later, they 'more than likely' ruled out its anything under hood (engine block issue, fuses etc), next step, removing dash. So after 4 hours not finding what the problem is I left as they had only allotted that time for the problem and I need to consider if I can afford them to 'explore' the problem when it could take ??? amount of hours to rip out the dash. Do onboard computers not help mechanics pinpoint problems? Can't this be narrowed down instead of figuring out what the problem is by way of elimination?

Hello, if rodents were present in the first place, I would suspect there is further damage to other wiring harnesses. I would strongly advise you to enlist you auto insurance company to help you with a claim as your repair costs will likely continue to grow as exploration of the cause of your concerns continues.
To answer the last question: No computer will tell you what the problem directly is. They only give codes that provide clues to systems that are malfunctioning. The burden of pin pointing the source of the problems lies in the hands of a highly trained technician, who indeed may need to remove the dash assembly to inspect wiring and components behind it.
Unfortunately it is impossible to discover rodent damage other than *hands-on* visual inspection.
Removing necessary components for closer inspection is just part of the process.
Once one circuit is compromised - it's a snow ball effect.
Additionally you’ll ned to rid the rodents from the vicinity vehicle is to be parked - and discourage would be critters in the future.
