Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hi There, I'm Clay a certified master automobile technician with 30 years of automotive repair and diagnostic experience.
From your description most likely the wiper motor itself has internally shorted to battery voltage. Remove the 15 amp ACCY fuse, if the wipers turn off the problem is most likely with the wiper switch. If removing the 30 amp WSW fuse stops the wipers the wiper motor module is at fault.
I hope this information is helpful. If you have any questions or comments let me know.
