Re: candidate for a window relay ???

Can you remove the door panel, and back-probe the motor connector to watch for voltage drop during operation?

Alternately, find another motor connector, and run large wires(12 gauge?) straight to the battery for a temporary test. Bypass any switches and connectors enroute. If this experiment significantly changes performance, then yes, a relay should help.
