my self leveling has stopped working since i did ltuned drop . does anyone know if their is a specific fuse for the self level motor or any suggestions on what could be the problem

 

umm..... what car do you have? i know on the is300 the autoleveling might stop working after lowering the car.

 

According to your profile, you have a GS4. On the IS at least, the autoleveling sensors are tied into the suspension, to measure how much the car is pitching up/down. Did a Lexus dealer do your L-Tuned work? They should know where the autoleveling sensors are, and should have made sure they were properly reconnected. Do you get the auto-leveling icon on the dash, or nothing at all? Do you hear the motors trying to move? (although the motors Lexus uses are very quiet) Any error lights?

I remember reading a post from an IS owner about this, I believe they eventually resolved the issue.
