The electric window motors draw a lot of current, are your wires big enough? The wires to my window motors were at least 14 gauge, and may have been 12 gauge.
Yes I tried big wires, tried with and w/o a relay. I even attached the electric motor directly to a fully charged car battery to eliminate all the wiring and the motor still seemed very weak.
I see that places like Gary Ball sell the same type of kit for triple the price. I wonder if they are better.
But I still didn't like how they fit in my door on a bind.
