As Kes72, I also have a problem with the front 12v socket/cigar lighter, the rear auxillary socket in the boot however works fine. My C Max is the 1.6 Zetec on a 07 plate. Looking at the fuse boxes as shown on topic 3971 my vehicle is fitted with thelater type fuse board with fuses numered from 100 up. Fuse 109 is listed as the fuse for the lighter and auxillary, this is ok as auxillary is working fine. Thought I had an issue with the cigar socket. so bought new and the plastic outer, but low and behold still same. Have checked for supply to the socket on the two cables below no supply?. Light for the socket however, lights up when main lights tuned on. Has anyone else had this problem, if so would appreciate you findings, as at present looks like I will have to run a new supply to the12v socket in the console.
