Thank rudeney, do you have any experience with how to detect the leak?Here is the oil you need:

In a pinch, you can also use Pentosin CHF 11s, but I do not recommend that as it's green and it stinks, so if it leaks, it's unpleasant.
You will need something to squirt fluid into the pump after removing the screw on the fill port. Something like a "barbecue injector" works.
Have you thoroughly read the Maintenance and Repair PPI sticky section ? Rear Power Window/Motor DIY ..Thank Rudney, finally, the metal panel was removed. The next step is taking the glass and the regulator out.
I really do not understand this guidance.
Can you help me step by step to take out the regulator.
1. Take the glass out
- The glass is attached to the regulator by 3 bolts. So how to remove these bolts? I can move the glass up a little bit so I can remove one bolt. Is there any way to remove the 2 remains? Can I use my force to pull it up and down to put the bolts at the holes in order to open them? I saw some clip guiding to open these bolts via holes but I see the opening gap is wide enough to use a wrench to open 3 bolts. Is this the proper way?
