2001 Chevy Impala Windshield Wipers

Hello,

This past fall, I had to take my car to the dealer for numerous problems and they ended up replacing the body control module. This solved most of the problems that were going on. Not long after the module was replaced, my windshield wipers stopped working. The wiper fluid sprayer also will not turn on. Do you have any suggestions as to what might be wrong? If so, is this something that I might be able to repair myself (I have very amateur auto repair skills such as oil changes and replacing brake pads). Thanks for the help.
