AZ - Saw your post and had some PTSD. I had to deal with a Mice-pocalypse when I bought mine a little over a year ago. It had been sitting in a field in Hood River for >2 years.
Great suggestions in here. Ditto the peppermint oil. I tried apple cider vinegar at first and should have just jumped straight to peppermint oil. Avoid peppermint sprays (that aren't oil based). They don't last long. You'll find yourself re-applying pretty regularly.
The majority of the interior had been used as a bathroom, including the upper side of the headliner
. The main nests in my car were located (from front to rear):
intake resonator box
HVAC blower fan
ECU kick panel was a satellite nest / local dive bar
Big nests inside the B pillars! Wow. Pull your trim and your seatbelts, you'll see clear plastic shields on the inboard B Pillars under the pretensioners/reels. Man the little sh!theads loved this spot!
Massive nest in the spare tire well. This was the mothership. They also clearly enjoyed using the NiMH pack as a playground. When I disassembled for LiBCM I had fun cleaning this too.
I documented a little bit of my journey here: Newbie...1 month in...and how the adventure has been going.
Best of luck to anyone going through it. It truly blows. But with some determination you'll make it to the other side and it will be glorious.
