Damnit, I just now this is gonna cost me an arm and a leg...

Ok, not long ago, my left turn signal started flashing faster. Usually means there is a bulb burned out. Before I get a chance to look at it (procrastinator I am), a few days later both signals stopped working. No "faster flashing"...just no flashing at all!

So I have Renee step on the brake pedal while I'm standing to the rear of the car. They're out too!

So I figure my dumb luck, both bulbs musta burned out at the same time. I pull the drivers side lens tonight and check the bulbs, but they're fine!

When I turn on the headlights, the tail lights will illuminate, but neither the brake or turn signal lights will illuminate.

How the he** do I track down an electrical problem?? I'm pretty upset right now because I called an automotive electrical shop and when told what my problem was, they said they can't quote me an accurate price, but "don't be shocked if the bill is over $500!"

FIVE HUNDRED DOLLARS?!? Are they mad?????

Guys? Anyone? Idea's? Should I post this in the classic forum too, just to get more idea's since the traffic is more over there?

TIA,

Stewart

A burnt bulb will make that side not flash at all. The flasher operates on heat.

Sounds like you need a turn signal switch. It's in your steering column. Not very expensive, I think. {I'm not sure how it is on a air-bag car.}

Do you mean the whole multi-switch? The one that controls the blinker, high beam, and windshield wipers? That whole assembly?

Heh heh heh...I wonder how daunting the task will be once I get the column off...

Steve, is there a volt meter or some other diagnostic tool I can hook up to the switch to check for current?

That's the one.

Yes, you would check the continuity through the switch.

Multi-function switch failure is common on Crown Vic/GM's Stewart.

You'll need to find the color of the wire to your left turn signal, by wiring diagram or just by looking at the wire at the lamp, then after you disconnect the turn signal at the base of the column you would probe the plug in with a multimeter and check for continuity between the power wire and left taillamp wire with the switch in the left turn position.

Sounds a lot more complicated than it is.

Do you have a multimeter?

Nope. Can you recommend a good one?

Sorry, Stewart. I missed this question.

Sears sells some pretty decent digital ones for $20-25. Even cheaper if you are willing to settle for analog.
