I have no cigar lighter hahe changed cigar lighter

replace the lighters themselves,if you use them for cigars,they get really hot and if you put them away b4 they cool,you will melt the wiring on the vback,pull them apart to check or try replacing just the handheld unit

The fuse could be burnt out, the lighter coil could be burnt out, or the hot wire or ground could be loose.

use a test light on cigar lighter, put probe in center of socket and the ground on outside of cigar socket or any other good ground. if power to socket, this will tell you if the cigar socket is bad and needs replaced. if it has power and lighter does not work, then its the heating element itself thats bad, the part that heats up! good-day !

If you are refering to the 40 Amp "CIGAR" fuse under the left rear seat, this is the "main" fuse for the lighters. There are 2 more in the engine compartment fuse block. They are marked "C/LTR 1" and C/LTR 2". They are both 20 Amp fuses.

The cigar lighter is installed from the back of the center trim panel.

To remove the center trim panel, open the ash tray and pull out on each lower corner. It will be hard the 1st time you remove the spring clips. Once the lower part is released, work your way up to the top, there are 3 spring clips on each side of the center trim panel. ( circled in black in the picture below )
When you get to the top, be careful how far out you pull, the Passenger airbag deactivation light is at the top, with 2 small wires to it. ( circled in green )


Once you have the center panel released, you can remove the HVAC connector ( clamp over type connectors ) or work on it in the truck.

Remove the cigar lighter connector, and release the locking tabs on the cigar lighter body. Pull the lighter plug through the front of the panel.

Their are three wires that should be hot to the radio plug the lights on wire the all the time wire and the key on wire. Your saying that the key on wire doesn't work but the other two are good. The number 20 fuse 10 amp is the cigar lighter and the key on power if the cigar lighter works the fuse is good the trunk opener works on the same fuse.

the BCM controls the lights, the cigar lighter will burn out at anytime so replace the knob and element

Look in your manual for the Power Distribution Box reference in Roadside Emergencies. It should be located under the hood on the driver's side. My 2002 Explorer has two power points on the center console and the 20A fuses in the Power Distribution Box for them are number 7 and number 9. They cost $3.99 each at AutoZone. The cigar lighter fuse under the dash is unrelated.

have you try a new lighter?

Check all the fuses with a 12 volt test light. Also does the cigar lighter work many times the same fuse that is for the cigar lighter also powers up the obd 2 connector.
