Please help. Can't find afs lexus number?
 

My AFS controller back on the passengers side rear axle is done. I have the flashing AFS light on the dash and the lights won't adjust or turn with the steering. I took the controller apart and water got in and rotted all contacts. Does anybody know the Lexus part number or where I can get one? I like the feature and would like to get it working again. Thank you, Jamie
