i made the mistake of purchasing the junkyard buckle, only to find out that the airbag sensor in it was deployed. now my airbag light on the dash is illuminated. i called the junkyard back and the fellow agreed to refund my money fortunately. there is really no way to tell this by looking at the buckle (at least this particular one looks *perfect*). word to the wise - don't purchase a used junkyardseatbelt buckle unless you know the driver wasn't jerked around in an accident. this sucker took about 2 hours (wasted!) time to install. there is a mind boggling number of wires and connectors and very cramped quarters under that d*mn seat. i now have a new buckle on order.
does anyone know what the procedure is to reset the dash airbag light? can i do it with an ordinary obdII code reader/reset tool?
not sure i should even bother posting this given the ovewhelming interest. but maybe this will help some other poor soul... here we go:
pretensioner on a good seatbelt should measure closed circuit (close to zero ohms). the pretensioner is the orange connector. the seatbelt-not-attached warning is related to the brown connector. in other words there are two seperate circuits controlled by the seatbelt. on a bad seatbelt in which the pretensioner has been deployed, it will measure open circuit (close to infinate ohms). how to tell if you don't have an ohmeter? look down the black metal barrel at the end of the unit; if the securing end of the cable is not at the very bottom of the barrel then it's been deployed - and it's no good. you can also tell by looking at black plastic sheething covering the steel cable between the buckle and the main housing; if it looks crumpled, then the cable has been retracted and it no good.
seatbelt buckle replacement:
following instructions are for driver sidereplacement. set aside approximately 1.5-2 hrs and god bless you for your patience.
1) put seat in full back position and unbolt both front bolt connecting seat to floor (10mm)
2) using electrical seat switch, move seat all the way forward
3) unscrew plastic pieces covering rear seat floor bolts (philips screwdriver)
4) remove four rear seat floor bolts (10mm)
5) remove electrical harness from car to front of seat (6mm)
6) tip seat on side inside car (no need to remove) and block up with a small cardboard box underneath to level seat somewhat. balance it so that you can get at evereything underneath while sitting in the passanger seat.
7) pry thin metal retainer, and pull electrical connector forward, un-clipping from seat bracket
8) using small flathead screwdriver, release two clips holding brown and orange connectors from seatbelt assembly from the electrical connector backshel and push out.
9) unsrew seatbelt buckle assembly (large torx)
10) cut cable ties to remove seatbelt buckle assembly.
11) install new seatbelt assembly in reverse order - use a couple of new cable ties to prevent the two wires from cathing on anything below seat.
side note: the dashboard airbag light (associated with code 33 = driver side pretensioner failure) will reset itself without fiddling with any computers

Glad you posted this and Thank You! Wife pulled up outside in rain sitting in car and yelling like crazy till my old mom saw her and came and got me. Wife was furious seat belt stuck and she couldn't get out!
I was having a great laugh!,
Followed your instructions yesterday and they worked very well. I took my old buckle apart and found, as expected, that the spring in the unit had twisted. I replaced it with the spring from a "just in case" passenger unit I got from eBay, and it's good as new.
