Car won't move
 

Hi, I've fitted a new esl motor, but when I put it all back together the car goes into drive and reverse but will only move slightly, similar to the movement you get when you put it in park. Has anyone encountered this problem or can anyone help?

Unfortunately that little ESL motor is not functional.

I think there’s two main failure modes. (1) The little motor in the ESL unit fails. (2) The ESL logic board gets fried.

So you might have #2.
