Fixed my driverside seatbelt
I had the same problem .... screeching seat belt that does not retract.
I removed the plastic panels to access and remove the seat belt mechanism. Using a can of WD40 (with the provided tube for the nozzle) I carefully pulled the webbing all the way out and aside to gain a clear shot at the outer portions of the spool and gave it several shots on both sides of the spool. Then I allowed the belt the retract. Then moved the belt in and out several times to make sure I got enough lubricant in place. I was very careful not to get lubricant on the belt. It now works fine. I will replace it soon though with a new one. I view this as just a temporary fix until I can buy a new one.
