This is for a 2.0 hdi but might apply .
haynes page 12.16 shows the lighter and rear socket.
there are 4 fuses.
Engine fuse box. MF8 70A
interior fuse box F3 5A
The fuse F3 is the one directly in the lighter line.
F5 is for the rear power skt.
MF8 if that blows then both will be dead along with many other items
F32 powers a speed sensor which then powers the BIS computer and then onto the lighter.
very complicated but I'd go for F3 first. there again is it the actual heater coil in the lighter that's not working or is an accessory power plug. Sometimes these have a red ring on them that prevents full insertion into the socket so they don't make contact.
