I re-vacuumed the carpet again. Had all orange crud from the roof lining all over it. Also had to clean out all the fluff and dust up the b pillars and inside the dash, now I’ve removed all the climate panel.
Will be replacing the seals around that with a PVC foam. Much longer lasting and better seal.
The ducts will also get new seals with a different type of foam seal.
Cleaned out the shifter and trans tunnel. Lifted the carpet from the rear and got all the bits out. The carpet doesn’t smell under there so was confident a steam clean will bring out the grot.
Of note, Thanks to doing this uncovered some flaws in the panel seals at factory. Two spots weren’t sealed so well. At all. This spot is looking down next to the passenger seat. That white bit is the garage floor you can see.
The other spot is here on the trans tunnel. Luckily neither areas had evidence of water coming in (somehow). So they will get sealed up.
