Alright. The hummer has been falling apart on the inside for a little while and I need to get some of this addressed. The driver side front seat lumbar support no longer works. I hear the motor working as well as a tasteful crunching noise of broken plastic. Also the passenger side front seat rear bottom tilting does not work. I get a click out of the switch and relay and the motor used to struggle to move, but now it isn't moving at all.
Is there anywhere I can get these parts without getting a whole new seat from the junkyard? The seats look similar to the ones in an 09 suburban but I don't know if they're the same. If they are, what is the part number. I would love to just replace the broken parts, but I can't find them online anywhere.
1 more thing. The locking actuator might be broken on the rear liftgate. I can't find any of those either. The cables just might need adjusted, but the whole thing may have just gone out.

Any help is greatly appreciated. I have been looking for a month for these parts.
