1990 Riviera Windshield wipers

I had my car in for a new fuel pump. Came back from the shop and windshield wipers no longer work. I checked the fuse, it was blown, and replaced it. They still do not work. I hear no noise from motor but was wondering if there is a module to check first before we pull the motor and replace it.

Replaced the motor...still doesn't work...any ideas??? Could it be the switch in the turn signal? Is this hard to replace?

It was the switch in the turn signal...it cost me $300 to replace it! Anyone need a windshield wiper motor?
