On a mk 1 C3 the pretensioners are in the inertia reels in the B post so no under seat connection for them.
First check would be to make sure the wiring is plugged in. If thats ok you could swap the reel over with the other side to see if the fault moves. If the belt is long enough you may be able to do this without unbolting the complete belt.
Make sure the battery has been disconnected following the correct power down procedure for 10 minutes before playing with any airbag connections.

You could also try; pull out the center console (where the stick shift or auto shifter is).
Under there is a little black and orange box with a yellow and white label, about the size of a pack of cigarettes. That's the airbag module. Pull the electrical connector out off the box and look for corrosion on the connector and receptacle pins.
I have found people spill 'beverages' all over it because right above it is the cup holders!
Give that a try.
