probably the clock spring inside the column is bad. they are usually fairly easy to change but can sometime be expensive to buy. i just did the wife's jeep in December and got lucky and found a clock spring for 50 or 60 bucks because her xj Cherokee has cruise control so its the more expensive one.
compare ebay, amazon, rockauto, and google for prices. you can usually find an oem part on ebay or amazon for cheaper than the dealer ship
here is the place to look for your part number, just put your vin in the box and type clock spring in the search and it will pop up. i tried it on mine so that is whats in the link
