The first thing to do is have the trouble codes pulled at ana Advance Auto or Auto Zone or a local repair shop. It will probably be free as most places do thsis for free. This will give you an idea where to go. The crusie control may have to be dis-engaged for now. Look for the fuse in the fuse panel diagram on the back of the box. If I had a diagram I would send you what the unti looks like so you could disonnect it from the throttle plate.
Look under the hood into the fuse box there for crusie control fuses asa well until you get the codes read ad have this repaired.
