There is no power to auxilary power ports, how can this item be repaired?

Check the CIG/AUX fuse number 20 in the rear fuse block. This supplies power to both the cigar lighter and the auxiliary outlet. Makes more sense to me to check this first before crawling around the dash and running jumpers for ground!

The answer is simple its a 1 wire system works just like the cigarette lighter and on the same circuit.You plug your device or what ever in to the port .The sides are the ground the contact point is the middle is HOT dc power .
The problem is the ground wire no ground no DC current .
Their is no fuse just the ground dosn't need a fuse .
The problem is you have to get at the back of the port witch is inside of the dashboard.
But its low so if you can crawl under the dash and repair there or run a jumper wire from a ground IE any peice of metal mounted to the body of the vehicle it should work again
