To be honest, I'm not sure what is the problem. This is the first car I work on, and the problem is the starter just clicks. I thought it must be the starter, so I took it to the mechanic. He cleaned it, after that clicked for a few times and then started, so there was no change, i was like okay it's not a big problem i just ignore it. It was okay for like 3 months, but then the click were more frequent, I bought a new starter. And just like the old one, it just clicks then start. For a few days it was okay, then it doesn't even start, even after i put back the old one. So I thought it has to be the cables. So there I am right now. I cleaned the battery cables, but the same happens. It doesn't start. The dash is working. The battery is working. The only thing I noticed, I sorted the cables and the fan for the cooling turned on. But when I tried from the ignition switch, the fan doesn't move. I don't know if it's just because I sorted the cables, but maybe I'm in the correct direction now. And also i will try the multimeter and soldering the wires together. Thanks for the answers! Cheers!
