Thank you for the reply can you please tell me how to remove the wiper arm cowl. I'll much apreciate it. thanks again

Usually one would post a followup question on the original thread. It makes it easier for others to know what the question is, and possibly be able to help.

There are some small screws on the top. They are either phillips or torx. Remove the screws. If the right side wiper arm goes through the part you are removing, remove the wiper arm. You will probably have to remove the weatherstriping (if equiped, if it interferes). Make sre nothing else is attached to it, and it should come off.
