About the heating engine

My friends, when my heater reaches the 3rd rank, it fuses. According to the information I got from here, the resistance of the heater motor should change behind the torpedo. I can insert the heating engine, but I need your help with the change of resistance. Can you help with both the picture and the expression?

If the fuse was previously removed and a lower fuse was replaced, it may blow due to it. Check whether the original and the amps are the same from the booklet of the vehicle. For example, instead of 20, 10 is installed, you can continue with 10 while you change it. Of course, friends who come to you can give ideas

I bought the car a week ago. When I bought it, there was 20 insurance. Do you know how many of these are originally sogorta? Thank you for your comment.

when this topic is available, it does not work in the 3rd stage and 1st stage in the heating, it closes, 2-4 works, I guess I would be glad if a friend who knows the subject also enlightens me from the day I bought it.

In this forum, some other levels of similar fault writing are not working in another friend. Someone removed the fault without knocking someone from the resistance.

hmm, I understand, thank you. Let me examine the past.
