Default 2005 Suburban Power Seat and Heater Not Working

Good morning everyone. I'm new to the forums and still learning how to navigate.

I have found multiple posts regarding this, but it has been a lot of hit or miss answers. So please forgive me if this problem has been answered 🙏😎

Ok, the problems... lol
~Driver side seat adjustment doesn't work.
~Passenger side seat adjustment does work.
~Seat heaters doesn't work on both sides.
~Airbag light is on (I heard this to be related to what's going on).
~Pedal adjustments work.
~Seat memory doesn't work, but makes a beeping sound when pressed.
~Nothing happens when the heated seat button is pressed even though I swear I heard a clicking noise one time in the door area.

What I have figured out so far. I checked the 30amp fuse under the dash and it's good. I have a connector that has been cut that I can plug in for the driver side seat adjustments that I can hook up my small jump box to. When I put power directly to the switch the seat adjustments work.

My next step is to pull the seat to look for any clear signs of problems. The main connector that everyone talks about with the orange and black wires being messed up appears to be fine.

I suck at diagnosing things and especially electrical issues. Thank you in advance for any guidance in this situation. Hoping to find some updated information seeing most of the threads I found were pretty old.

God bless,
Ramzo... 🙏😎

if you have memory seats its all controlled by a module. have the codes read by someone who has a scan tool that can access the memory seat modules. a cheap code reader won't work.
