Chevrolet Repair: 1988 Chevy Nova, ford pinto, chevy nova

Question
My son has a 1988 chevy nova. It needs a wiper motor. I once replaced this on a 75 Ford Pinto. How difficult of a job is this one and where is it?  

Answer
it should be under the cowl panel at the bottom of the windshield, on the outside. it could get a little difficult without the right tools. you might want to consider taking it to the dealer for this one. good luck to you if take this on. let me know how it came out.
