replaced 2002 dodge durango,but the air bag light do not go

have had my 2002 dodge durango in the shop for more than 2 weeks, the air bag light will not go off?? We have replaced a seatbelt and all the wiring? Now they say it is getting too much voltage???

Your vehicle will require a scan tool for the proper diagnosis. I will need to know the code that the scanner produces before I can help you with your specific problem. Throwing parts at a problem, especially an airbag related problem, can get REAL EXPENSIVE FAST.
