My Skoda Octavia '97 lighter don't work.

Compressor relay

From the Haynes repair manual:
'access to the relays can be obtained after removing the drivers side lower facia then remove the two plate screws (one either end) and lower the plate complete with relays'. Some relays are at the rear of the engine (the second box left to the nearside suspension strut) as your looking into the engine (under a cover)

The fuel pump works off of these fuses/relays:
Pin 5 goes to fuse no. 32
Pin 10 goes to fuse no. 34
Fuses are fed from relay no. 109

Hope this helps, a diagram of the footwell is here:

dear there is two fuse for radio < first fuse is at the back of the radio under the connection socket , the second fuse at side fuse box No. 27 10 A

Sounds like faulty coil. Check this on a diagnostic machine at a garage and you will get the answer.

open the drivers door there is a removable panel at the end of the dashboard with fuses behind it there should be a piece of card inside the panel cover telling you which fuses are which
