Hello there, I’m having technical issues with my Mercedes c230. Pretty much my left and right blinkers aren’t working!! But if I push hazards they flash??!!! Windows won’t go up or down ?? Also my key doesn’t lock or unlock the car... Curious as to what caused this? Electrical problems and the cost situation?

First of all, check the vehicle battery voltage - it should be about 12.6v at rest, no less than 11v while cranking and 14v at idle.

The turn signal issue could be a bad combination switch. For the windows, do none fo them work using any of the switches on any door? If so, maybe a low voltage issue?

The remote locking not working is one of two things. First, check fuse 8 on the rear panel in the trunk. If it's blown and a new fuse blows, then you have a bad alarm siren. It is located under the fender shroud behind the front right passenger wheel. If fuse 8 is good, you have a bad antenna amp and that will cost more than the car is worth to replace.
