Do you have to take steering wheel off remove indicator unit 1997 ford fiesta?

No, you generally don't have to remove the steering wheel to replace the indicator unit (turn signal stalk) in a 1997 Ford Fiesta. Access is usually from behind the steering wheel column cover. However, you will likely need to remove the steering column shroud (the plastic cover around the steering column) to get to the indicator stalk. Some models might require slightly different procedures, but removing the steering wheel itself shouldn't be necessary.
