Check relay and or the fuses need checked for blown fuses or switch went bad or the grounds for it are bad or loose or The one he replaced it with had those issue so either get another used one or put the old one back in and live with light on or what I would do first is try the old one again and see if those things start to work again if so you know it was the computer he put and if not you no you need to look elsewhere.

    The car has a rough idle, slow pick up when starting out at lights, stop signs, etc. While driving the car it shakes. It seems like the engine is straining. Also, the check engine light is on.
