I’m a cocky, know-it-all, bastard. I worked 35 years on European cars. I took one look at the instructions in the manual and thought, “What a load of baloney.” I got a friend, lube, string and went at it the way I have installed dozens of windows in the past. 2 hours of cursing and repeated attempts, it wasn’t in!
My friend went home.
I then sat down and carefully read the manual. 45 minutes later, the rear window was in, including the locking strip… by myself!
The only change I made from the manual’s instructions was to use plastic pry tools not dull metal as suggested.
