where is it - I want to fix it this weekend.

I've seen some diagrams suggesting it's under the passenger seat, some under the driver's seat, some by the ecu.
lots of conflicting information.

doesn't work at all at this point not sure if it's unplugged or what but yeah.

I've heard I may need the durametric to reset it.

help!

 

Per the 2006 C2S coupe wiring diagrams it's under the driver's seat. No guarantees for other years/models though - cabs sometimes mount things in different spots.
