Im not the most mechanically inclined individual...
I just bought those new contour type replacement windshield wipers and wanted to find out how to remove the OEM windshield wipers?? Pitiful isnt it...

 

Look on the box of the ones you bought it should have instructions. If it doesn't then its real simple there is a tab that you have to squeeze on the mounting point then just pull the wiper blade down the arm tword the truck. The new ones will just snap in and your done.

 

Didnt see the tab... Got em in (now that we probably saw the last rain of the season in Los Angeles).

Thanks
