Welcome to 2CaroPros.
I attached a picture of the relays you are referring to. They are in the under hood power /. Relay distribution box. See picture.
Now, to determine the cause of the problem, you really should have the computer scanned for diagnostic trouble codes. The codes related to this system would be B codes and require a higher level scanner to identify.
Let me know if you have questions.
Take care,
Joe
