Driver seat and pedals stuck on preset 2

[Big Mama]

Thanks gave it a go and no luck. Tried disconnecting seat, which is a PITA with seat all the way down, tried disconnect battery no luck. Do y’all know where the memory module is? I’m going to try disconnecting the wires to the memory buttons for the heck of it. Know any manual methods to move seat without screwing it up?

Check the fuse box, underhood #69 60amp

also check # 25 left side dash fuse block

and looks like there is also a circuit breaker in the drivers left floor junction box, -circuit breaker 3 -CB3

Checked your grounds? Isn't there a ground wire under the seat for the motor and/or controls circuit(s)? You may need to unbolt the seat and tilt it back to have a clear view of the underside.

I know I saw this and I think it was traced to the memory controller. My 07 Denali only does this when my wife hits her preset now it’s stuck for 5’1” woman and I’m 6’2”. Anyone recall this? I’m headed out now to dive in looking for codes and fuses. She’s no longer allowed to drive it. Happy Fathers Day All.

Mine has been acting up too. Sometimes the seat won't go back upon exit and won't come forward and pressing the memory buttons does nothing. Other times it works just fine. Code comes up B2375 5A and B2375 06 which is for the Horizontal Position Sensor for the left seat. Last time I looked, that was part of the Memory Seat Module (MSM) (don't remember for sure) and that thing is embedded inside the driver's seat. Needless to say with summer here, I'm not touching it until the weather cools.

Manual controls work and we tested the connector and it was fine as well. I wonder if the movement or people's feet causes a loose connection?

if it’s the same one the ground is on the B pillar about 8 inches off the floor and it looks good I didn’t check under hood fuses or relays or the others Wes mentioned. Will do this morning. Thanks

if it’s the one I saw on the B pillar it looked great but I didn’t notice the junction box Wes mentioned so I’ll double check. Thanks

Thanks James, I’m on the other end with it stuck all the way down and forward so even getting to the front bolts is a bear. Going to try some things this morning and I’ll report back. Does anyone know if there’s a way to manually move the seat?

Use external 12v source to power the motors individually.

A Tech-2 might do it or make up some wires with (alligator clips?) out to the battery and power the motors direct like Chris mentioned.
