Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. The two most common causes of this are the control module and the wiper switch itself. Most of the time the issue is the switch. I would recommend replacing the switch assembly on this. It can be diagnosed with a voltage meter and checking some wires which is what the shop should do to find out what the problem is. Please let me know if you need more help.
