Thanks for information. My car is the E38 model 1996. There is no fuses under the back seat id checked there. I did find more fuses however in the battery compartment in the boot on the right hand side, in the compartment there is some black insulation stuck to the side panel & the fuses are behind that. The cigar lighter fuse is on its own 30a curcuit & had blown. I changed it & is all working now. Thankyou for you responce.
