I purchased a 1999 XJ8 recently and found the windsheild wiper does not work. Listed below are the steps I've taken to isolate the problem.
I located two fuse boxes under the bonnet on the left side, all the fuses are good.
I disconnected the the windsheild wiper motor connector under the bonnet and applied voltage to the motor. Both low and high speed worked.
Checked voltage on the harness from the windsheild wiper switch. Found that one pin always reads 10 volts and noted the other two pins read zero volts. These readings remained the same for all the windsheild wiper switch positions.
Checked the voltage at the windsheild wiper switch, I found 12 volts on a few connections.
Did I miss any thing or should I replace the switch?
