The BAS/ESP ETS & ABS lights go on and off.....they are mainly on all the time except when it is sometimes cold. At first they would intermittently go on and then off but now they are on almost all of the time. Someone told me there were parts (about 12 - 20 bucks each) I could replace but have no clue where to look or what to get. Any suggestions on this problem would be appreciated. Thanks!
