Hi,

There are two fuses I need you to check, the PSD 1 and PSD 2 fuses. These fuses power the power doors. Both fuses are in the underhood fuse/relay box. When you check them, in addition to checking the fuse, confirm there is power to and from them.

Here is a link that you may find helpful:

Additionally, I attached a pic below of the fuse/relay box. I highlighted the locations of the two fuses and three relays I would like you to check. Note that each fuse powers one or the other side of the vehicle via the power sliding door module. The relays are dedicated to the power door latches.

Here is a link that explains how to test a relay:

Note: If other relays have the same part numbers, switch them to see if that makes a change. It's easier than testing the relay and circuit.

Let me know what you find.

Take care,

Joe
