No, they don't mean the same.
"I'll get the car working" means you plan to fix it yourself. "I'll have the car working (in no time)" means you're confident you can fix it!
"I'll have the car worked ON" means you are (probably) going to take it to a mechanic. (It's the mechanic, not the car who will be "working" in this case).
