Default Bonnet opening cables

My ZT has been suffering from a stuck closed bonnet. Iíve replaced the cabin cable and the splitter box and the bonnet opens now. The o/s catch is later in releasing than the n/s, so I suspect a stretched cable. Can these forward cables be replaced without removing the front bumper and slam panel, just by loosening stuff and tilting the slam panel up? Any shortcuts/ pics of the front cable and catch arrangement would be appreciated. Iím now all to familiar with the rear cable to splitter box!

Cables don't stretch, I suspect the catches may be gummed up. Try loosening the 2 bolts either side of the bonnet catches a little.

In my experience Michael, cleaning is what's needed not cable replacement. Mine are the originals, now 25 years old!
The catches mounted on the bonnet closing panel (I don't do slamming ) become contaminated with a mixture of old grease, dust and dirt making a paste similar to finely chopped black olives that inhibits the smooth operation of the mechanism.

From memory, removal of the front bumper and bonnet closing panel is unavoidable but if you do the job thoroughly it won't be necessary again.

I'm sure I read something quite recently of someone who replaced the catches by undoing the bolts holding the headlamp panel to the wings, inserting a couple of wooden wedges to increase the gap and managing to remove the catches. Would save hours of work ...

Thanks for the responses. I've just had a look, and you can just see the cables/ mech if you peer through the gap. All seemed to be located properly and reasonably clean. I sprayed in some silicone lube. Moved the retaining bolts (undid a bit and lightly re-tightened) I also adjusted the interior panel as that was catching the lever. The off-side bonnet catch still operates later, but I'll see how it goes for a while...

I managed to do it without removing the bumper, removed the radiator location brackets and slightly "springing" the slam panel. It's a bit of a faff but doable.

My latch boxes were quite gummed up, a good clean and new grease worked. I did find that if you tighten the the box mounting screws a bit too much they pinch the latch mechanism, which can result in the catch not resetting.
