I have an 03 sport coupe. Problems started with drivers side window going up sluggishly. After a couple times noticing that, the window would go part way, then go all they way back down. It did that twice, then stopped working all together. I disassembled the drivers door, ruled out wiring damage, so cleaned and lubed the regulator mechanism. When I plugged it in to test, it ran good in both directions for about 4 cycles, then stopped again the full up position. Then the passenger door stopped working all together. Checked all fuses - nothing... Anyone got any experience here?

Have you followed the trouble shooting steps in the FSM?

Negative. Where can I get my hands on one?
