Clio 2002 1.4, Airbag and SERV light on?

Hiya, hoping someone can help with fault on the clio.

I'm suffering from the airbag and SERV light that alot of other people are.

Took the car into the local garage and its says Fault code 180, Front side sensor circuit passenger short circuit.

I had a look under the seat at the wires and gave the connections a clean up before i took it in but light stayed on.

The mechanic said he traced the wires under the seats and disconnected at all connections and they came up with differant fault codes so its prob not those.

If it helps i just cured the leaking sunroof problem a few days before. Could it have anything to do with that maybe. Next step is an auto electrician and however many hours labour they want to charge for.

Any help would be appreciated.

Cheers
Steven
