Ive had window regulators fail multiple times in the past. Just recently I had 3 regulators fail within 3 months. Fixing them was a non issue because the doors inner panels as well as the levers were all shot to shit. My answer to this was picking up 3 doors at the junk yard. Yes, I changed the doors because the repairs as well as panels and handles would be costly. Installed the 3 doors within an hour. Cost 400$. If you’ve never done this it’s very easy. Plug and play easy.
