The fuse box in this car is fiendishly located behind the glove box. To access it, you first need to unclip the strut that controls the glove box lid’s action, unclip the two sides of the glove box where it pivots (there’s a plastic tab on each side) pull the glove box inner down and then you should be able to see the fuses laid out deep inside the dashboard. Next to the access panel, there should be a folded chart showing which fuse does what. There are some excellent online tutorials on how to do this.

If this chart is missing (and it’s possible as it’s a loose-leaf sheet of paper) there are lots of online guides to show you what fuse protects what circuit.

To remove or replace the fuses themselves, I’d recommend a specific set of long-nosed pliers designed for this job as there’s very poor access to the actual fuses and getting at them by hand is going to be a pain.

The engine is probably worn and needs honing and new rings.

Some run-flat tyres are marked that they can't be repaired, but that's not necessarily correct we've been told. Run-flats can be repaired providing the sidewall hasn't been damaged by being driven too far after the tyre deflated. There are tyre dealers other than Bridgestone dealers who have the equipment to remove run-flats from the rims and repair the tyres. Bridgestone have an equivalent conventional tyre to your run-flat and these can be fitted to your car.
