W126 - '87 560SEL - Driver's Seat Back adjustment moves forward, no recline

[chinny4290]

Hey all. Need help with my Driver's Seat Backrest adjustment, '87 560SEL

Problem: It moves forward, but does not recline. I can hear the relay click when I try to recline it.

Switch: OK, all switches work, except recline.

Module: I don't think it's the module. I can save position memories and select them with no problem (when I move the entire seat bottom forward and back, up and down, as a test).

Anyone have any tips? Most of the searches point to a door switch problem. But I don't have a problem with my switch since I can hear the relay click when I try to recline the seat back, no motor whir.

Again, moving the seat back forward works (it's really upright and borderline uncomfortable).
