I have a 2003 2.7. The spoiler and boot release appear to be on the same fuse - D7 - 15 amp. Have you tried replacing that? If not, perhaps that's the easiest first step.

Interesting. There are more threads on cracked valve seating ring issue.... Also an '02, and also Cyl 4 & liner crack as a consequence. My #4 piston rings are seized, and likely the additional radial pressure from piston/ring initiated the sleeve to crack . However, interestingly, there are no signs of a broken seating on the #1 cylinder , but I also see that there was some hard debris in the chamber (see picture of the damaged #1&#4 domes/pistons) , causing piston and head to be deformed - yet the rings are still ok, and piston would likely work again. The real question to me here is where the debris in Cyl # 1 could have originated ? Can a parts of the broken intake valve seat from #4 somehow be transported to #1 cylinder ?? How likely it is that the damage may have been primarily triggered by sth. other than just a valve seat quality issue for this model year??? So far I thoroughly sonic'ed and inspected 99% engine components w/o finding any obvious damage/emanating hard debris material. The crank cradle assembly is the last item In question here, but which I am hesitant to dismantle if the likely hood of the root cause there is low. All rods move smoothly and show no bends or other damage). I just wanted to clean the cradle from the oil/coolant mix and just re-use. Otherwise , it looks like, likely getting engine casing , one head and at least one piston replaced is what will likely get this baby running again. BTW- if sb. has a 3.6l casing in good used cond. for sale - please let me know. Thanks.
