Hood latch is broken on my 1979 buick riviera

Miguel, 1993 Buick century hood cable broke. With a flashlight, you will have to lay under car and reach up where cable runs into latch and pull the latch mechanism/lever to unlatch hood. If not comfortable doing this call a locksmith and they will have it open in seconds. Check the attached links,instruction and guides, Good luck

YOU SHOULD HAVE UNDER THE DASH(OR ON DRIVER'S DOOR) A LEVER TO OPEN IT FROM THE INSIDE.

You may need a professional to get this hood open, and it will likely need to be on a car lift. Try this if you are handy, try removing the driver side fender well liner for access to the latch.

On a 1995 Buick Riviera, the fuse box is located under the hood in the engine compartment, just behind the passenger side headlamp. A detail of the fuses in this fuse box can be found on the inside cover of the box when you open it. Hope this helps!

There might be several problems:

1. Cabling to and from handle and latch is loose or stretched (normal wear) or broken. Replace and/or adjust
2. The latch is dirty or bent/deformed. Clean and lubricate
3. The latch needs adjusting, lubricating. Clean and lubricate
4. Misalignment of hood due to: wear, or slight bump/accident, nudge. Check for alighnment!

Try having someone pull up the hood while you pull the lever. This is a quickie only; then do items mentioned above...

if it broke at the dash,cut the cable housing down to get to the cable and pull on it with pliers,
if it broke at the latch you can still open it you will need two long skinny screwdrivers and patients

cut the sheth around the the end of the broken cable to expose the inner steel wire core, then pull on that with a set of vise grips.

The problem is a bad ambient air temp sensor or a broken wire to that sensor. The sensor usually is located in the front of the engine bay on the support for hood latch, between the outer grill and the radiator/condensor assemblies.

if its broken at the handle inside the car use a pair of pliers to pull the silver cable if it is broken outside the car there is a black plastic shield on the underside of the car, remove it and the lack will be visible use a screw driver to release latch
