I AM STUMPED. My beautiful 1998 v70 2.4L joy (with 115k) has a driver seat motor problem.

The driver seat control, control board, motors are not working. I've confirmed that all 16 pins on the control unit are working. Proper Voltages, Proper Function when activated (i.e. voltage drop). I hear "clicking" within the control board. I have checked all ground wires for continuity with the chassis. Yet with any of the funtions (seat forward/back; backrest up/down; rear edge, back edge, memory, etc), all I get is "clicking in the board". I've tried (3) other boards: one was from a 1996 850 (same connectors and functions and control unit, but a few different internal components (i.e. switch models)), and today I went to a dismantler that I trust (for parts on my '92 940gl) and he loaned me a functioning control unit and control board. I know that it was functioning because as luck would have it he was installing into 1998 V70 T5 - the seat was tilted but grounded and I watched the functions work. We tried the two components on my car and still the same clicking in the control unit.

I have 12.35 volts at the one Red/Yellow lead into the control board (this same connector has a couple ground wires all grounded).

Can anyone help please? I'm thoroughly frustrated with a car that I
