This brief video describes how I replaced a broken hood release latch handle on a 2000 Chev Suburban. The replacement part used to fit this model was Dorman part #03335, and it seems to work fine. Hopefully it will last as long as the original part.
If your handle breaks, you should lubricate the cable slides and mechanical system since corrosion and increasing mechanical resistance is likely underlying.

Before any kind of repair you should consult the dealer repair manual for additional information not available from various multimedia sources. Never trust a single source for critical information. Any misadventure you encounter if you decide to accept the risk of home repair is your responsibility.
