The hood latch on my 1989 Chevy S10 Blazer occasionally gets stuck (usually when it's cold out). I tried lubing the latch and spring to no avail. I'd like to increase the tension on the cable to get a bigger "release"....but it does not appear to be adjustable. I tried moving the little metal stopper at the end of the cable but it doesn't budge. What's the trick?
____________________________________________________
The metal stopper is usually permanently swaged on to the release cable, and is not removable.
The end of the cable housing is probably clamped to a bracket near the latch arm. If so, loosen the clamp and slide the housing away from the latch arm until the metal stopper is in the desired position. Then retighten the clamp.
Also, check for misalignment of the latch probe as it enters its nest when closing the hood. That could cause a sticking latch.
Good luck.
