Power window motor wiring '87

Pass window quit working halfway down, found yellow wire broken at motor. Short on time, so twisted off blue wire too. Bared a little on each and jammed in alongside recessed terminals. Window up for Winter!! How do I release the old wire terminals still on the motor? Are they spade with a release tab on back? Thanks! Happy Birthday USMC! Thank you and Welcome Home all Vets.

Yes they are some sort of reverse french spade connectors. They slide out the back after you remove a tiny plastic cover. I replaced them with regular old spade connectors and left the lid off.
I honestly don't know if it possible to do it with the window motor still in the door, maybe. I drilled out the rivets, I pulled the motor and put it back in with small bolts and nuts.
