I just replaced the seatbelt in my 95. According to Volvo, the warranty is 5 years. The unit is simple to replace. Just make sure you disconnect the battery and do not reattach until you have all the wires reconnected. The unit costs about $280 at the dealer and I couldn't find it anywhere else. It is a simple replacement. There are two bolts, 14MM I believe, and a torx screw. Depending on whether or not you have power seats, you'll need to remove the cover on the side of the seat. Lift up on the front of the control unit and once it gives, slide it backwards. Remove the 12MM bolt holding the belt. You should replace the bolt. It needs to be replaced at 14lb-ft of torque. The bolts holding the unit need to be torqued to 35 lb-ft. It took me about 20 minutes to complete the whole procedure.
