Hood Open light will not go off - 2007 Chevrolet Silverado 1500

I would say you have a faulty pin switch under the hood. These can be purchased at radio shack and shouldn't be too hard to remove and reinstall.

There should be a switch the hood comes in contact with, much like a door switch for the interior lights. That switch may be broken or stuck.

Remove the bulb from under the hood this will brack the cirecut and if the inside lights goes out its a bad bulb there is no system that is that specfic to the hood light that will effect how the vehicle runs. But its kind of like my refrigerator is that light on with the door closed . I couldn't resist saying that .Not to make sport of you its likely a shorted connection at the bulb a ground issue or a bad bulb it can't have any big effect on the vehicle running correctely

use a flash light shine it center front grille where hood is.look down center hood where grille is you should see small opening where your hand can fit through to open the hood latch.i remember most 70s cars you open hood from outside around front grille area.

Try having a friend lightly push down (lightly so not to damage) on the hood while the cable is beiung pulled. If that does not work look through the grill. On the left side (drivers side) of the latch there is an eyelet where the cable goes to. Use a long screwdriver of something to push it towards the radiator support.
One the hood is open grease the latch! You can also try to loosen it some. Look at the pin on the hood. There is a lock nut. Loosen the lock nut and turn that pin out some. Too much and the hood will rattle as you go down the road.

Depends on the make/model, but most manufacturers use a simple one-wire hood switch. When the hood is open, the switch connects the wire to ground and the hood open indicator lights up. it's easy for a manufacturer to incorporate a ground sense circuit into the alarm. Basically, if your hood switch has one wire to it (or sometimes two wires), leaving it unplugged could solve your problem with false triggering the alarm. Although some cars have two hood open switches. In any case, make sure to check that your hood is closed securely with the hood open switch disconnected.

I would replace the switch itself. It is likely dirty or faulty

With the hood open have someone push the switch manually as if the hood is closed and see if the light goes out. If it does the switch is out of adjustment. Readjust the switch and you will be done. If it stays on when doing this you have to check the wiring for a pinched wire.

Try disconnecting the hood sensor. Now I can't remember if the sensor goes open when you open the hood or if it goes closed. Try by disconnecting it and see if the hood light goes out if not then jump the wires. The hood sensor is just a small pin under the hood. Looks like a door jam switch

Someone just successfully helped me with a similar problem. IF the cable is Not broken, ie: still taunt when one pulls the hood release lever in the car, then the latch under the hood is simply stuck. Try this. Have someone bounce/press down on the front center of the hood where the latch is located to relieve spring tension. At the same time have someone pull the Hood Release lever inside the car. This may pop open the front hood. Then after the hood opens spray WD40 on the hood latch to rid the rust which likely is the cause of the problem. BTW...don't know what you mean about the Oil Light comes on. You don't need the engine turned on to open up the front hood, at least not on my model (2door sedan).
