So I recently got a car from a buddy ( 2004 mazda 6 3.0L), and I have a huge amount of electrical issues that all went wrong at once so I figure there has to be a common problem.
The list so far is this.
Guage cluster lights
Rear tail lights
Ac
Speakers
Steering wheel audio control.
Trunk release
Rear defogger
And I am sure there is more.
P.s. all fuses are fine.
