I dont have the owners manuel nomore. Do u know how to find that fuse

Use the fuse box diagram link I posted.

That fuse is good also

Ok - it’s time for some TESTING! Using a 12 volt test light - check for power at the fuse with key on - if ok - check for battery power at vehicle connector - IF no power - find and repair open circuit.. Good luck!

Ok i will do that tomorrow an let you know what happens. Thank you
