Windshield wipers on 1994 Chevrolet Lumina

How do I get my windshield wipers back working properly. I had my windshield replaced and now the wipers seem to be out of sync and hit each other.

Asked by for the 1994 Chevrolet Lumina
Are the the wipers that cross over each other? If yes, then the best advice is to take it to a qualified service center and have them retimed. The cross over models have a square aluminum stub and a tapered knurled shaft that is inserted into the wiper arm and are very hard to remove and readjust.
