My cig lighter doesnt work, cant find the fuse?
 

Anyone know where to look? I looked in the fuse box and there is nothing indicating cig lighter.

Any tips on this? (not to mention the wiring is in an unreachable location behind the dash to trace)

Stick a power port device in there first. Might be a bad cig lighter. That would be a lot easier than tracing wires that I have no idea where they go.

Oh, beleive me, it was not for the cig lighter, it was for an old radar detector I was going to use. (so yes, I plugged that in and no power)

Oh well, I tried

Does your radar work in another car? I will try to help when I get home tonight if someone else doesn't chime in.

Do our cigarette lighters work with the ignition off??

smoke em if you got em.

"Do our cigarette lighters work with the ignition off??"

Nope - unless you have two like I ended up with.

This is the diagram from an SC.

It shouldn't be that far off.

Er.....I guess I should try that too, but my cellphone charge doesnt work in my P-car, yet it does in my other cars.

I seem to recall some discussion about how 911 cig lighters are a different (larger?) size than most cars, and that is why many phone chargers don't work. Maybe a search will help. I wonder if someone, maybe the dealer, has an adapter.

My lighter socket does not hold the V1 plug very well either. I ended up wrapping some rubberband around the plug, making sure the metal parts of the plug are uncovered. It made the plug a snug fit, and it sits just fine. Makes me realize I could just take some effort and wire it up to the ignition. It would look cleaner too...

Is it ok if I just splice the wire into the same wire that gives power to the radio, or should I really go into the ignition wiring?

You got some expensive equipment there. I would buy a Radio Shack 99 cent inline fuse and double your protection. I'd also go to something that doesn't have a lot of draw or doesn't get used much. Windsheild wipers, maybe, but I bet the cig lighter has it's own fuse in the panel.....If we only knew which one it was.

I know that on early models the cig lighter goes through a 6 pin connetor on it's way to fuse # 4, hope this helps,Randy

white fuse (2a) fourth from the rear of fusebox

I'll check it out tonight, thank's!

5 amp fuses are yellow
8 amp fuses are white
16 amp fuses are red
25 amp fuses are blue

Colors can fade/change with time; check the chart in your owner's manual.

Well, on my car the blue fuse #6 was blown (just found this out tonight) I thought I had checked them all yesterday)

#6 is labeled cig lighter along with "rear wiper" wich I dont have

So I swaped it out with the only replacement fuse I had (white) it blew out as soon as I pluged in the cell phone charger

So I figured, well sinc eI have to get fuses tomorow anyhow, lets try the "rear fog light" (I dont have any) fuse as a replacement just to see if it works now, it also blew!

So now I figure I have a short some where, I just dont know how in the world I am ever going to trace the wire since it is in a harness along with like 15 other wires.

(tomorow I'll replace my rear fog light fuse, don't know why but I will anyhow)

The # 6 fuse on the 10 fuse block or the 9th fuse counting from the the windshield to the front of the car. This fuse controls your windshield wipers, washer pump and cig. lighter. it's a 25map.

Are your windshield wipers working?

Well, that answer to that question just created more questions.

Windshield wipers work (good thing) - Yet the #6 fuse is blown (bad thing)?

Is this an indicator that my wiring might be a little tweaked?

Sorry Bigrubberjeep...

NOT the windshield wiper but the rear defogger. Look at the fuses in the engine compartment. I was looking at another issue for a fellow owner.

How does one test the rear defoger without fog?

ha ha ha,

In the engine compartment (drivers side) under the black cover there are 3 fuses. Actually they control the rear "defrost"

Boy am I having a bad day here.

Ok FOCUS here, what are you asking or sugesting I do?

Very good question. I would say leave your car out overnight but that's not the best suggestion. Any luck yet on finding the problem?

Nope

OK....

If you look inside your plastic fuse block cover (front trunk)

From the top....it's labled: 1 through 3
1 through 10 and
1 through 8

You want to look at fuse # 6 on the 1 through 10.

On the cover it is labled:

air blow, rel. heat rear wind, cig.-light

it takes a 25 amp fuse......

next: In the engine compartment there are 3 fuses under the black cover on the drivers side. Those fuses are related to the rear defrost..ie. the heating lines in the back window.

Check those fuses. They should be (from the top)

25 amp, 25 amp, 8 amp.

I'll raplace all the blow fuses and make sure they are the correct amprage. Then I'll come backformore tips.


Mind you, I tried a 25 amp fuse last night on #6 and it blew as soon as I turned the ignition on. (so?????)

I don't have a clue as to why you're blowing fuses or how to track down the shorts, but you may want to check to make sure that your alternator isn't overcharging and popping fuses. Overcharging can occur when the voltage regulator poops out. To check out the overcharging thing, put a voltmeter on the battery with the car running. The meter should read between 13.5 to 14.5. If it's more than that, you have an overcharging problem. On another note, the size of the cigarette lighter plug is in fact larger than normal. Some radar detector manufacturers (like passport) actually make multiple sizes of plugs to address this issue which is common in European cars.

Thanks for the tips here, as for the plug size, I am aware of it, the plug actually fits well. but I will check the charging system.

Fuses don't blow from overvoltage. They are current limiting devices. Something on that circuit is shorted. See if the center wire on the back of the lighter plug has popped off and is touching something. 25 amps is a pretty fair draw...
As RoninLB would probably suggest, get a 25A circuit breaker, wire 2 alligator clips to it and clip it to the fuseholder tabs. Saves replacing those little fuses while you're troubleshooting....

I had a similar problem with my lighter - tried to charge my cell phone and discovered it didn't work, kept blowing fuses as fast as I could pop them in.

In my case the problem was the hot lead had detached itself from the connection on the back of the lighter and was grounding out. Getting at the lighter is not that hard - you have to go at it from the trunk side - not the dash side. Once you get the blower motor out you will be able to see the back of the lighter and can start to trace the problem.

As to the size of the lighter socket - one cell phone I had years ago actually came with a plastic adapter for use with "certain european made cars". I remember laughing at the concept (didn't have a Porsche then) and tossing the adapter in the garbage. Now the guys at those unavoidable "wireless phone stores" just give me a blank stare when I ask about those adapters. Crap - all the great stuff I 've tossed away over the years.

I would never use the lighter for my V1 - but it suffices for the cell phone charger. You just insert the charger at a certain angle and it works fine - no big deal if you lose contact like it would be with the V1.

Good luck
