just brought an xj 94. the ABS light stays on, the passenger side front disc does not let go properly i think that is the problem? the pads i will be replacing tomorrow as they are falling to bits, i assume from the heat generated from the constant rubbing. any ideas? also the window washer does not go (front one) is this a common problem do you replace it with a generic one or get a genuine one? how do you know if the back seal on the motor is on its way out? i think there is a small oil leak by the sump where the oil drain hole is but not sure?
