How do I know if my police interceptor is working in my car I have a 99 crown vic with the police interceptor and my car doesn't drive like it has one.

SOURCE: 99 crown vic police interceptor steering wheel??

i have ran into 2 issues in these vehicles---if it binds while sitting still also, check the steering shaft, i have found the u-joints in the shaft tighten up and binds dangerously tight---if they are free, sounds like you may have a steering box issue or restriction in a line---hope this was helpful!!
