Hey friends!
I have been trying to fix my car's AC. Let me tell what I have done since now:

Before I started to do anything, the blower motor was working when I push it on its middle.

I have changed the blower motor resistor. The product I bought is in . Nothing changed. However, at the first try, I accidentally put the resistor upside down since I am an absolute moron. Do you think the resistor can broken down because of this?

After a while, the blower motor started to not work even if I push it on its middle. It only reacts a little bit, turns like a 1/16 of its orbit then stop again
After that, it started to not react to anything at all.

Then I changed the blower motor's itself. The link is in . Nothing changed.

After that, today, I have switched R1 and R3 in the fuse box. You can see the image. It also did not work. I suspect that I might blown up the relay. I also changed the AC fuse.

I tested the cable of motor with a multimeter, it works fine. However, I did not checked the resistor cable. I don't have my multimeter on me now, do you think should I check it too?

Is there anything else that I can try by myself? Or should I bring the car to a mechanic? Can you please help me?
Thank you so much!
