The hood release latch located under the dash of my 190e has all of the sudden stopped working. When I pull it there is no tension. No I can't open the hood.Is there a way that I can tighten it somehow?

 

maybe the cable snapped off the latch. if thats the case then use plyers wen u wanna open your hood

 

I second that motion. The wire itself also may have snapped. Look underneath and behind it. You sould not have much trouble openeing the hood without it, all you need is a long screwdriver to pushthe latch back and open it.
