Thanks for your response and helpful information Kasekenny1. I forgot to mention my car is a couple if it makes any difference. I have a few questions.
Are you referring to the buckle being a one time use or the seat belt? If the seat belt tensioner is deployed would the seat belt be locked and not retract? The buckle in my car does not appear to have a tensioner but the seat belt assembly does have a tensioner. I took the seat belt assembly off today to take a look at it to see if there was any issues with connectors being loose or off but all seemed fine. During this I read a sticker on the seat belt assembly saying it has explosive contents. I also took the seat out and checked for a tensioner on the buckle but it doesn't have one at lease not that I can see. Buckle is attached to a metal bracket attaching to the seat. Didn't see any cartridge tube that could indicate a tensioner.
I'm a little confused about the seat belt being bad because it's still operational as in it it's not locked and it retracts and also locks if pulled abruptly. I think it's either a malfunction in the tensioner or maybe something in the wiring/harness as you mentioned. I'll try to test the harness and seat belt per your attached instruction. Just have to figure if I can test it without the tools noted in the attachments.
Thanks again for your help on this.
