both cigarette lighters are not working and the 15amp fuse is not blown on 1990 Lexus LS400

I got a 1990 Lexus from my dads friends dad. Every things great with the car except that after using my phone charger without problem, ( in both cigarette lighters). All of a sudden they both lost power. I checked the fuses but they are okay. What else could it be and how to do I fix? Thanks ; )

Asked by for the 1990 Lexus LS400
There is a blue 15 amp fuse in the fuse box marked CIG feeds both lighters with power, inside car under dash steering column side.
i checked it and it was good....I read in the book something about maybe checking the fusible link. Does that sound right?

did you check the fuse in the charger end?? there is a fuse in there as well.

Hi Roy, Thanks for your reply. Do you mean in the car charger itself? Because I tried the charger in my friends car and it worked fine.
