2003 Toyota Corolla WIPER LINKAGE ASSY

AFTER REPLACING MY WIPER LINKAGE ASSY WITH OEM PARTS. I CANT PUT THE 2-WIPER HANDS/ARMS INTO ITS PROPER PARKING SET POSITION (ALL THE WAY DOWN), IF I DO THE WIPER WIPER CRASH OR ROTATES DOWN. RIGHT NOW WHEN THE WIPER STOPS WIPING IT ENDS IN THE MIDDLE OF THE WINDSHIELD OR I PUT IT THAT WAY SINCE WHEN I PUT IT DOWN IT IS CRASHING, BECAUSE WHEN THE WIPER START TURNING IT TURNS TO THE LEFT OR DOWN RATHER THAN TO THE RIGHT OR UP. HOPED TO HEAR FROM YOU SOONEST, PLEASE.
I THANK YOU.
