Any good garage would check your fuse panel for a bad fuse. You might find a wiring diagram at Autozone.com for FREE. Just register your car and scroll down to the wiring diagrams.
Check either wiper motor by providing a ground wire and then put bypass power to the correct terminals. The new motor should be forced to work this way if it is any good. Then that would mean if it works, that the switch is not getting power or the switch is bad. Check for a bad wire from the switch to the harness. Do a power OFF continuity check on the wires running between the wiper motor and the switch to eliminate a broken wire.
Behind the fuse box is the control unit that drive the wipers flickers and anther stuff what you need is two 12v 10amp relays and a 12v mega tester the wipers is working in negative striker from the steering control follow the wiring to the computer box and then from the wiper motor then insert the relays it is quit a meson if you are not technical rather replace the computer box or let me now and i will draw up a drowning for you how to bypass and work Manuel
Hi, Check relay switch. Could be bad.
There are two coils on the windshield wiper motor. One for fast and one for slow. The wiper switch has to ground the output to the motor, for the speed desired. You can test that pin on the connector for ground. If no ground then the switch is probably bad.
You can ground the pin yourself, if you have a good schematic, and see if that fixes the slow input.
Hope this helps.
Normal fault is the wiper motor
