Is the cable broken or just the handle that you pull? If just the handle, you should be able to pull the cable with a pair of pliers. Have someone push down on the hood just a little bit while you pull. May also need to pry the hood up also. If and when you get it up, lubricate the latch with anything, oil, WD40, something. If it is broken where you cannot get to, you may be able to get the grill out, or possible get the cable to come thru the grill and pulling on it there.
