Hello all,

In other threads, I have asked questions about start, idle and running of this car. Turns out the throttle body had not been rebuilt so I had that done. The cold and or hot start was still off, so I replaced it with a good used one ( as far as I can tell).

The trouble I am having now is that the car does seem to start and run better, but cruise control still does not work, and I have lost any function with the power windows, sunroof, turn signal, hazard lights and even interior light. Is all this bad in the new to me body control module (aka idle control ecm) or is this tied into something else? How can I begin to troubleshoot this?

I very much appreciate Any guidance. First beer is on me.
