Citroen C3 - Seat Belt Not Clicking (Repair)

Citroen C3 2002 1.1 had an issue which drove me crazy. The seat belt didn't engage into the housing. I added a bit of WD40 to the housing, got it in and out a few times, and now it works better.

I had the exact same problem on my C3. Thank you for the video, it solved the issue! :)
