Power Steering

I own a 2003 town and country minivan. Recently I had power steering fluid hose replaced and rack & pinion replaced. Since then I lost my cruise control and horn. I took back to the shop and told them about the problem. They looked at it and told me that they could not figure out what is causing that problem and told me that the work they completed had nothing to do with this problem. Any comments.

They could have hit or cut some of the wires because all of those things run through the stering colum.
