Hood latch cable broken on 2001 cougar, unable to relese hood

First, try smacking the hood at one of the front corners while someone else pulls the release handle. or even after you've pulled on it. if that works, once open, adjust and lubricate the hood latch assembly. if it still won't open, and it's the cable and not the latch you'll have to replace it anyway, so instead of removing the grill, cut the cable behind the pull lever under the dash where you can reach it. then skin the outer cable insulation away from the actual steel cable exposing an inch or two of it. then holding the insulation and plastic housing with pliers, grab the steel cable itself with pliers and pull it to open the hood. then replace the cable. the further you can reach up under the panel the better your chances of getting past the broken part of the cable and avoid removing the grill. you might also be able to gain access from up under the car if you're lucky.
