Hi guys, a couple of moths ago my abs, bas, and asr warning lights on. So yesterday I decided to put a new brakelight switch, but after I installed it, I turn the car and put it in drive, and sure enough the stupid warnings came back on, Is there anything else that I need to do to get rid of them? Also as soon I put the car in drive and roll a couple of feet, I feel some grinding on the pedal, like the abs was coming on, I had the front brakes replaced about 2 months ago, so I doub that's my problem. Please somebody help! Jose.
