Trying to replace the aux cigarette lighter assembly in an 2008 Chevrolet Tahoe. How do I take apart the dash to get behind panel?

There are actually FIVE cigarette lighter/ Auxilliary Power Outlets shown in the wiring diagrams for your vehicle.
The Instrument Panel [1] Accessory Power Outlet (Cigarette Lighter) is protected by the "LTR" Fuse (# 53 - 20 Amp) in the Power Distribution Center (PDC) in the engine compartment.

The Instrument Panel [2] Accessory Power Outlet is protected by the "AUX PWR" Fuse (20 Amp) In the Instrument Panel Fuse Block on the left side of the dash.

The Center Seat Accessory Power Outlet and the (two) Center Console Power Outlets are protected by the "AUX PWR 2" Fuse (20 Amp) In the Instrument Panel Fuse Block on the left side of the dash. NOTE: If your vehicle is not equipped with the Center Seat Accessory Power Outlet, or the Custom Floor Console (optional), this fuse position will most likely be empty.

if the fuses re good then you will need to remove the lighter and check for power behind it. some lighters have a fuse link built in and if thats blown will need to replace the whole lighter assembly.

{: ) hi! Check out the rear fuse block which is on the left side of the luggage compartment, behind the left rear wheel well. Look for fuse labeled CIG/AUX 20amps.

The fuse for the cigarette lighter is fuse #13...20 AMP ,

There is a fuse block under the hood...look for #13 there.

There might be another fuse block under dash bi drivers left foot.

good luck

I suggtes check the position CIG LTR for Cigarette Lighter. The underhood fuse block in the engine compartment on the driver's side of the vehicle near the battery. Lift the cover for access to the fuse/relay block.

To remove fuses, hold the end of the fuse between your thumb and index finger and pull straight out.



Also, in this link could donwnload the Owner's Manual for the 2005 Chevrolet Tahoe.

Hope this helps to solve it (remember to rate and commene this answer).

In earlier model vehicles, the cigarette lighter is on the same circuit as the dash lights/ radio/ interior lights. Maybe it's not labeled as cigarette lighter, try other fuses. also, there should be a fuse panel both inside dash and under the hood. Also, sometimes there can be an in-line fuse right behind the cigarette lighter.

The fuse is in the engine fuse compartent and should be labled aux pwr 20 amp fuse(yellow)

It's the 20 amp fuse marked OUTLET under the hood.

if you are talking about the one near the radio, just pull back the dash panel, it snaps in and you can access the lighter

check fuses,also the socket it self could be wore out they are easy to replace,
