Windows are moving fine, as well as all other eletrical parts. I
suppose any additional load on alternator will slightly decrease rpms,
but in my case something is not doing a good job keeping them up.

Good point! I do have this happening sometimes. I'll try to clean ISV first.

Thank you very much!
