How do you fix Mondial 3.2 dash lights?

I have the same problem on same car - it showed up after picking up the car for service for something unrelated to electrical, so I'm not sure if they just broke or it was related to the work done. I am going to try to fix first and then take it back to the shop if I can't. I'll let you know what happens. You would probably have been response posting this in the tech section rather than modern car discussion.
