That’s all. If you know how to make the post better, write in a comment.
The engine light keeps coming on and off on the dashboard. This in turn has started affecting acceleration and headlights lights don’t come immediately I turn them on. What component of the fuse box on the left side of the engine malfunctioning could be causing this?
Hasn’t anybody noticed that the designation does not match the diagram on the cover for the under dash fuse box that has 31 spots? The cover show is number 23 as the cigarette lighter fuse your destination indicates number eight is a cigarette lighter fuse which is incorrect.
Fana is not working Automatically
Mine is a Yaris 2007 model now my indicators aren’t working actually which fuse doing that
