1998 XJ8. The hood release will not work on the passenger side. How can I release the hood?
It sounds like the hood cable broke or became unattached.
To open the hood you would need to get under the car and reach under the front of the car to see if you can release the latch manually.
If you can't then the car needs to be bought in to an automotive professional to have the hood opened up and have the hood cable replaced or adjusted.
