I have a couple problems with this vehicle. Not sure if all can be answered. To begin with both front and rear heated seat have no power. Second, rear 12volt accessory power outlets have no power. Third, the third-row seat does not fold. And last rear climate controls located in the center console/armrest has no power. I have no experience at all with wiring and/or checking diagrams. Hopping I can get some help. I’d really appreciate it.

We can help be we only handle one problem at a time, please start new threads for the problems except for the heated seat which we will handle on this thread. Let's start by checking the fuses for the heated seats, can I ask if any lights work for the seat heaters? We need to check the fuses that run the system (4) BCM5, LTD HTD CLD SEAT, RT LTD CLD and the IPC fuses. Here is a guide to help and the fuse locations in the images below:

The fuse panel is at the left side of the dash. Check out the images (below). Let us know how it goes.

Okay, there are 2 main grounds to the system which can be cut or undone. Here is the clement controlled seat wiring diagrams which show the grounds, G133 and G218. Here are the locations of the grounds which must be checked. Check out the images (below).
