How do I stop the blinker noise from sounding even when the blinker is off?

I have a 2000 chevy blazer and the blinker sound is always on! Its making me crazy!!! I'm hoping its something simple, the truck runs great so I don't think its worth taking it to a mechanic who will charge me $200 to flick a switch or twist a knob. Please, someone help before I go insane!!



By the way, I've already tried changing the fuse, no dice.

The turn signal flasher and hazard flasher on that truck are one and the same. It does not look like the standard two pronged round flasher used on many cars, it is actually a rectangular relay located under the dash on the passenger side. Just flip on the turn signal and follow your ears.



If the flasher is clicking with the turn signals and hazard flashers turned off, the problem is very likely the Multifunction Switch. This is an assembly, bolted to the instrument column, and includes the turn signal switch, hazard switch, high/low switch, and the wiper switch. It is a common failure part, I've replaced a lot of them, many under warranty. There was a recall on them. The labor time to change it is 1.4hours, GM part # is 26100838 for a tilt wheel, costs $432.92. It's 26100837 for a non tilt, costs $195.02. You can probably get an aftermarket one for about $65. You'll need some small Torx and inverted Torx tools to do the job. With the right tools, you don't have to remove the steering wheel to replace it. There is a Torx bolt on the bottom left side that backs out in to the steering wheel. But if you have a short enough driver bit, you can get it.

Check your doors, it often is the same warning...
First, check the electrical switches on the doors. If they are good then look for broken (or shorted) wires on the same circuit.



Also check your emergency blinkers switch. Sometime if this is %26quot;ON%26quot; it makes the blinker sound, but usually it will indicate this by also flashing both of the turn signals.



If you do not have a circuit tester, go buy a cheap tester at Radio Shack. These can be invaluable in hunting and finding electrical gnomes in the car and in the house.
