Chevrolet Repair: wiper repair, chevrolet caprice classic, 1991 chevrolet caprice

Question
I recently had my wipers changed on a 1991 Chevrolet Caprice Classic. I usually do it myself, but the were changing the oil, so I let them do it. Afterwards, while running the wipers to clean the windshield, the driver side wiper started to malfunction. At first it came all the way up as it's supposed to, but after a few times it would only come about half-way up if that far and the right wiper would hit it, so I've got a problem I think they caused. However it happened, I need to know if this is a problem I can handle myself, or if I need to take it to the shop to have it repaired.

Thanks so much,

Nicolas

HI NICOLAS,  MORE THEN LIKELY THEY FORCED THE WIPER ARM UP OR DOWN WHILE INSTALLING THE WIPER BLADE CAUSE THE PIVOT BOLT TO LOOSEN OR HURT THE SPLINES ON THE WIPER ARM OR WIPER TRANSMISSON PIVOT. THE TRANSMISSION OR LINKAGE IS UNDER THE COWL BY FRONT WINDOW..TO CK LOOK AT THE PIVOT ON THE WIPER ARM DOWN BY THE SHAFT,THIS IS WHERE THE WIPER ARM IS ATTATCED SEE IF IT IS LOOSE AT THAT AREA,IF NOT YOU WILL NEED TO LIFT UP THE COWL PANEL UNDER THE WINDOW AFTER REMOVING BOTH WIPER ARMS AND LOOK TO SEE IF THE LINKAGE WHERE IT BOLTS TO WIPER MOTOR IS LOOSE OR IF THE LINKAGE IS BROKEN..YOU WILL SEE IT. JUST TURN THE WIPERS ON AND WATCH THE LINKAGE MOVE TO SEE WHERE THE PROBLEM IS..YOU SHOULD NOT HAVE TO PUT THE WIPERS BACK ON TO CK THIS.IF YOU ARE UNABLE TO FIND THE PROBLEM LIKE THIS THEN PUT THE WIPER BLADES BACK ON AND WATCH..I DO NOT KNOW WHAT METHOD HOLDS THE WIPER ARM TO THE PIVOT. THERE MAYBE A NUT,WHICH IF IT IS IT MAY JUST BE LOOSE..SEE IF THERE IS A COVER OVER THE PIVOT ON THE WIPER ARM,,IF SO LIFT THE COVER AND CK..IF NOT A COVER THERE THEN THERE IS A LITTLE LEVER UNDER THE DRIVER ARM,LIFT THE ARM UP AS FAR AS IT WILL GO ,LIKE 1/2 WAY OR SO AND PULL THE LEVER OUT FROM UNDER THE WIPER ARM AND LIFT THE ARM OFF THE PIVOT..THIS IS JUST FOR THE DRIVER SIDE. THE PASS WILL PULL OFF,IF IT DOES NOT HAVE A NUT HOLING IT DOWN..USE A VISE GRIP ON THE WIPER ARM PIVOT POINT AND ROCK BACK AND FORTH WHILING PULLING UP..
