2010 Chevrolet 2500 Extended Van can't get hood open. Inside latch flips open, but still can't raise hood.

Should be under the hood fuse compartment

If you can get a spray nozzle under the hood try soaking the latch with WD40 then push down on the hood where the latch is while someone pulls the release handle at the same time, it may work.

Raise hood,have some one go pull hood latch and you look at latch and see if it releases,if it doesn't then cable may need replacing,I would'nt completely shut hood cause you may not get back open,also check hood latches bolts and latch for something bent or broken.

My '02 astro van hood latch used to stick shut also. I was able to open it by having a friend operate the pull handle under the dash while I picked up on the hood. After I got it open I used some cleaner to degrease the latch mechanism and lubed it all with a good penetrating oil. It's worked like new ever since. I suspect I'll have to relube it every once and a while just to keep it working like new, after all it's a moving mechanical part.

is it attached to the hood latch on the inside of the van if so it may be the latch under the hood if its not attched on the inside attach it to the hood latch puller

im taking a guess that the inside latch your refering to is the latch inside the cab of the truck, if so inspect the cable, can you see the metal cable inside the black housing, if you do take a vice grips and grab onto tightly and pull, this should release the mechinism same as if you pulled the latch, otherwise if you can see the cable within, crawl under the front of the truck, between the radiator and grill, reach up to the latch and disconect the cable that comes from the cab, it will be the only cable coming to the latch assembly, as you remove it, it kind of just clips in place, you will see what it pulls to release the latch, grab a screw drived and lightly force the piece over to pop the hood, i know it can be frustrating from experience, took me a while the first time, and they sure dont give you much room to work with, but a little patience will pay off with this , wish you the best of luck!

it can be unbolted,but it sounds like your primary latch could be giving you problems. have some one play with the hood release (pushing and pulling) while you release secondary latch and pull up on hood. if you get it open spray all moving parts with wd40.

Will start simple:
If the handle is broken inside car, find cable end pull with pliers, the handle is replaceable by itself from dealer or junkyard.

If you are pulling handle and hood will not pop up, have a helper pull up on front of hood and lightly bump down on hood near the latch with their hand or fist(careful not to dent) while you pull on handle and it should popup, now lube it before you close it, the hood may then need to be opened and closed several times to work lube into latch(this sticking is common when latch system is not lubricated regularly).

If the before mentioned does not work...the cable could be detached at latch which is usually caused by: lack of lubrication and/or trying to open hood in winter after going through carwash.
Now things get trickier and you're best finding a shop that can raise the car up so that they can jimmy it from below.

if you try to look inside( between the hood and the grill) , you will see the latch with two bolts holding into it.remove the two bolts using a extended tool.then the hood will released.
