Cigarette lighter quit working was the start

Check your in dash fuse panel for the 4wd fuse and make sure it is o.k.If it is blown replace it and see if these all work again.

If this fuse is good test one terminal that this fuse seats into for 12 volts DC or power with the key on.If you have no power then the fault is the electronic ignition switch with it needing replaced.This is not the ignition cylinder but the electrical switch itself below the key cylinder.

Thanks Pete

This is a difficult question for me to answer myself here.

I will open your question up for others here to see if someone else can assist further on this as there may be others here that may have more info on what to check or do with this issue.I hope you can get this resolved with ease.No need to reply to my last post here unless it is a last resort as it will keep your question locked to me and others will not be able to view it.If you feel you want to continue to work with me on this feel free to reply at any time but keep in mind in some cases it can be difficult to fully diagnose or help repair this without seeing your vehicle.

Thanks Pete
