Hi,

I attached the wiring schematic for the wiper/washer circuit below so that you have a reference.

I'm not seeing a relay in the schematic. If I recall, it is controlled integrally within the motor.

Can you explain what is happening? If it isn't working at all times, there is a solder joint that is known to crack in the motor assembly's circuit board. They are not too hard to repair.

If that is the case, the wipers will usually work sometimes and not others, so let me know.

Take care,

Joe

Hi,

Absolutely, you can. Also, if you have a chance, check for the tag either on the driver's door frame or under the hood that provides a production date. That way I know if I should check different model years.

Take care,

Joe
