what year is the car?My 97' PA has a place for cell phones on the drivers seat next to the floor about the middle of the seats, you'll see a black plastic cover.Pull it out and there ya go..Power for your cell.
P.S. Check the voltage before plugging n the lighter,then if it seems okay, change out the whole unit if it's blowing a fuse.Sometimes they short out.why,I don't know. GOODLUCK
