Any of the fuse or fuses are blown out and causing this issue.

There are multiple fuses depending on your fuse box , which is depending on your level of spec on car, so you will have to check all possible areas.
Fuse box number 1 passenger side under bonnet:
- Check / inspect the fusible links .Locate Fusible links on passenger side under bonnet next to battery .The numbers SA 4 , SA 5 start from left hand side front of fuse box and count along until you come to fusible links 4 and 5, next SB3,4,30,49, SB3= 25A, SB4=25A, SB30= 50A, SB49= 50A, same fuse box as before.
Also look at fuses on top in same fuse box, you will see No of fuses beside fuse usually starting with an F.
Fuse box number 2 side of dash panel( driver side)
- For this fuse box you will have to remove cover on side of dash panel, again fuses are No on plastic part of fuse box, SC6= 5A, SC28= 20A, SC38 = 15A.
Check the fuses in the fuse box.
Fuse box number 3 located in boot area on left hand side behind trim panel.
- In these fuse box check fuses SF1 = 30A, start from left hand side and SF1 is 1st fuse.
Properly check each and every fuse and fusible links in the fuse box.Yes its time consuming to inspect each and every fuse,but that's the only procedure to confirm.
The problem is most probably the fuse and next possibility is wiring,but that's rare.
These details will help.
Thanks.
