Peugeot 307 sw ignition switch fuse keeps popping????sometimes the car will start and work normally but other times the dash lights illuminate but nothing works and the car wont start. replace the ignition switch fuse under the bonnet and the car will work for a few days perhaps sometimes it pops straight away. the car is a 2005 307sw 1.6 16v auto thanks in advance

You don't buy them buy size, you buy them for the vehicle. It is mentioned in the 3rd link though.

Is it doing anything else like the dash clock resets itself? Check all of your fuses. My bet is if the clock is resetting itself every time the engine is turned off, the fuse running that circuit is also the permanent power supply to the immobiliser and central locking.

I don't have specifics on that vehicle because it is not sold here in the US but most newer vehicles have a "Delayed exit" feature that keeps those components active until the door is opened.

Check ground and 12v supply for all the affected bulbs. Check fuse with proper test light. Is there a separate relay for right and left lights?
If there is, try switching them.

This is due to the loose connection of wires.

I had same problem with wifes 307 estate but also had ABS light showing, removed cover on near side front wheel arch to check ABS ECU and found a wire fitted with a fuse that had blown, replaced fuse and speedo now working, ABS light still showing but am working on it, but now the ignition will not switch off and sometimes the engine continues to run on so we have to stall the engine to stop itas soon as I fix these problemsI intend to sell the car on, it has been a knightmare I suggest you do the same

Try replacing the relay switch. Check and see if you have a Relay for the headlights/lights for your vehicle... sometimes the relays can end up bent and corrosion can settle at times...not sure why, but its happened to me several times in different vehicles...good luck!
