I took out my cloth seats and put in leather buckets and back seat now my airbags light is on how do you reset the light 2006 4 door dakota

 

You can't reset the air bag light, unless you have a code reader that will read and clear SRS codes. An advanced code reader is not exactly cheap. Your issue is most likely the weight sensors in the passenger seat. Even if you simply cleared the code, it would return because the seat weight sensors need to be calibrated. Did you notice the sticker under the passenger seat?

It says:

"Weight sensing system in the seat must be
reinitialized using a special service
procedure by a qualified service
technician after seat removal or any
service of mounting bolts."

You may get lucky and it clears itself in time, but that did not work for me.
