How do you remove the airbag on a 1995 Ford Escort wagon 1.9 in order to replace the gas gauge light?

You shouldn't have to remove the airbag in order to replace the gas gauge light. The steering column is held up by a couple of retaining bolts. Remove these bolts and the steering column will lower enough that instrument panel will come out easier. The steering column won't drop to the floor when you do this but will hang in midair. If you have a tilt wheel, you might have to adjust the wheel tilt to allow the panel to come out easier. Don't forget to remove the steering column cover though.
