Hi, I would first start by checking the 13mm nut that holds each wiper arm at the base. There may be a plastic cap over it, remove the cap. and try tightening the nut. If the nuts were loose at all, this was likely the problem.
If the nuts were tight, you'll need to remove the access panel on the firewall to see the wiper motor, and then check with a volt meter to see if it's receiving 12v.
If it has 12v at the motor and it still doesn't work, the wiper motor will need replacement. These commonly go bad.
