Clio 1.6 RXE ('99) Both Rear Doors Lock Failure

[synic]

Hey all,

I have had my Clio now for just over 2 years and apart from the usual wear and tare replacements and a new TDC sensor it's been fine. Just recently though both the locks on the rear doors do not open anymore.

The cental locking is working fine (both front doors open and lock fine) and I can hear the click from the back doors but the "snibs" will not pop up and as such the doors stay locked.

I was going to try and take the door covers off and have a look to see whats going on but with the doors staying locked I cant get to the screws.

Anyone any ideas on how to get around this??

Any help is appreciated.

Thanks
