Did you check fuses and relays??

Check your fuses! The easiest way to check fuses is to pick up a simple fuse tester at any hardware or auto supply store. Then you touch the tester's probes to the tops of your fuse and it will light up if it's good. This saves you the hassle of having to remove the fuse and hold it up to a light to see if it's good. For like $15 you can get a small kit of common fuse sizes and a tester, just ask the counter person for what you need.

I check some of the fuses but I think it's one of the big fuses

And I have a tester it's just a basic one
