Help with finding a part
 

This may be a dumb question. I need a drivers side backrest adjustment knob p# A1248211758 and also drivers side headrest adjustment knob P#A1248211958 . When I try to cross reference P# on fastlane it doesn't match up, their part numbers are different and always start with a W, ******** az is the same. Can anyone tell me the part numbers for those 2 items that I can buy on fastlate or anywhere else?
Something is going on with my epc, it is failing to initialize after 80% loaded.

The first # you gave is item 11, the second is item 14.

I had to check a 124.131, threw me off for a bit.

Sorry, I guess I am not asking the right question, so on fastlane their passanger backrest knob is under P# W0133-1641943 drivers side is not listed, what would corresponding P# for drivers side switch be on fastlane if the actual P# is A1248211758 ? W0133....?
I am confused

Not all part warehouses use the factory numbers, you'll have to talk with someone at Fastlane.
