Well, no replies, so I thought I would put what I’ve done. Turns out MPI will get this fixed up since I’m insured. I turned the car over to a remediation shop and they are going through the car, checking the wiring and upholstery. They have so far confirmed that the wiring is clear of chewing, confirmed the vents and heating system is ok, and they sent the back seats to an upholstery shop. The next step is to pull out the front seats and carpeting. I’ll update this post when I get more info.
