The Relese lever is on the left hand side under the glove compartment.
With a crowbar
the bonnet release lever on my 1991 205 is underneath the glovebox on the side by the door, and when the bonnet pops open, there is a small catch roughly in the centre, push it up (towards the bonnet) and pull the bonnet open.
The bonnet release lever is at the foot of the front passenger.
Hard to find - but on under the glovebox, tucked away
down by the accelerater
Using a small lever in the car.
the bonnet lever is under the steering wheel it should have a red handle
passenger side under glove box there is a pull lever, this will release your bonnet.
have you tried getting sum 1 to push dawn on the bonnet and puling the lever ??
Open the passenger door and look up to the left in the footwell. Here you will see the release lever. Pull it backwards then go to the front of the vehicle and slip your fingers underneath the partly released bonnet feeling for a small lever. When you find it push it up and lift the bonnet open.
Get somebody to push on the bonnet whilst you are trying to pull lever. This should do the trick then lubricate all moving parts of the catch mechanism.
