Tools needed to replace the cigarette lighter fuse

In order to replace the fuse, we need a minimum set of tools, which includes:

• Small tweezers - will allow you to conveniently pull out the fuse and insert it into its place;
• And a new fuse will be required - it is very important that the fuse itself matches the model and year of manufacture, and has the same voltage as the blown one. If the fuse parameters in most models are the same on Corollas of different years of manufacture, then their appearance may differ significantly from each other.

No further funds are required to replace the fuse. The only other thing you can take is a small rag that you can lay on the floor of the car and also wipe the fuse panel if it gets dusty.
