Can't figure it out. No power to cigarette lighter or rear 117 15a fuse. Fuse is in good shape. Tried new fuse, same thing. Is there another fuse up front or on the sides that might be out that is affecting this one?

Zerocarpileup

Any ideas?

nauticalx

no idea but I would start pulling each fuse one by one and checking them to see if one doesn't check out

Does your car have any aftermarket audio or radar equipment installed? I had no power on my rear outlets and when we got into it, realized either the audio or radar equipment was wired incorrectly off my cigarette power line.

Did it just start happening/ is it a used car? etc.

Zerocarpileup

Well yes.I was using the cig light for amp turn on wire. All wired and fused correctly. Can't imagine what kind of damage occured if any. So how was it "wired incorrectly" and what did you end up doing to resolve this.

Zerocarpileup

Could there be a relay associated with this fuse?

I don't know. The tech found the wire was teed off somehow and he rewired it for me. Don't think there was any issue with the fuse.

It may be the cig lighter unit itself. Some have a fuse link in them. Take a voltmeter or test light and see if there is power on the fuse itself. There is a small spot on each side on the top of the fuse that you can touch a test light to. Hope that helps..

I'm getting no voltage from the fuse nor the inside of the fuse mounting location. A fusible link you say. I wonder where in line that thing would be.

Check R relay

davetfft

I'll check!

This happened to me. On the driver's door, check one of the buttons called the override switch, which disables certain functions in the back seat. Press it and you should be good to go.

davetfft

it's worth a try!

konigstiger

If override switch is activated indicator lamp should be on.

Just bought a used S class with this issue. Lighter inop, as well as analog clock and driver's side dynamic seat. Yes, fuse #43 is good. Frustrating.

Zerocarpileup

Might have not noticed yet but does your headlight switch work? How about the buttons next to the command screen? You might need to change out the clock. The clock seemed to be the problem for me. Switched it out and it solved every issue.

where is this switch located exactly or near by ?

If I am not too late.

Override switch is located on a Driver Door - where you have your windows controls.
It would be located closer to your elbow, further from palm, when you rest your arm on a door handle.

I just fixed mine it's a relay you get to through the back seat arm rest. Its this one ill post a picture. However be warned I changed my now and about a week later I was driving around and my car went into some mode where I couldn't change gears I couldn't put neutral I was stuck in the middle of an intersection for 7 hours now my key doesn't register to my car I don't know what the **** is goin on

Maxvel_ua

limp mode maybe?

After years of putting up with this problem this solved it lol I checked fused swapped relays checked the real cig lighter wiring and all it took was me turning off the rear window lock on the driver door arm rest lol I had it off because my husky who usually resided in the back seat is a master escape artist hahaah oh how I miss these forums God bless you all.
