Windshield weatherstrip seal broken.. how to fix it?
 

Hi,
the lower part of the rubber trim/seal/weatherstrip of my 2006 Mazda Tribute windshield is broken...
by broken I mean there are part missing...
I was wondering, is there a way to fix it by myself or is too complicated?

I noticed that the rubber is attached to the plastic part that covers the wipers engine... does it mean it's all one piece or the rubbery seal is a separate thing?

if I bring it to a bodyshop will it be expensive to fix?

if anyone had this issue and wants to share his experience would be very much appreciated...
