Quick question.. How hard do I have to pull on the retainers to get the door panels off?
I've yanked, pried, and wished until my hand was full of little sparklies saying "No can do boss" all to no avail.
I don't want to break the door panels.

Edit: Ignore this. After getting fed up with no progress in the matter I decided to brute force it. I honestly have to say this took the most effort of any door panel i've ever encountered.

 

Get the tool just in case for the future. Works on any panel and makes it super easy to remove.

 

I have one in my auto lockout kit. I ended up actually breaking a couple of the tabs on the door panel itself. But it's a sacrifice I had to make to fix my power window.
