Driver's seat

[palmettodrive]

Power driver's seat on 2009 328 i works intermittantly. Works about 5 percent of the time. Swapped out used switch and seat control module but same results.
Did some initial inspection of wiring under seat but nothing obvious. Any thots?

I suggest run wires from the voltage supply on the switch up front, leaving a meter on them while you drive.
See if the voltage holds steady.

If it does not, then you chase up stream.

If it does hold, perform load testing while driving to see if it's a current issue (less likely?).
