If both lights come on while driving, it could be something as easy as the blue relays under the battery. You'll need two of them. They're roughly $20 apiece.ahukill wrote:Brake pads worn light came on. It took two days to get pads etc. In that time, TCS light and Slip light come on and stay on. They are not right when the car starts. I am looking to sell this car and see if someone may want it for parts. It is really good shape. May be the age of vehicle. Any ideas? Does the TCS need to be replaced? Thanks!
