Intermittent turn signal
The turn signal on my 2000 C5 has been a little flaky lately. About 20% of the time, the turn signal doesn't come on (either left or right signal) when I want to make a turn. Usually I just keep driving and the signals work fine at the next turn. Has anyone else had this problem? Any ideas what could be causing it? My first instinct was to replace the turn signal fuse...but I want to get some input before I go down that path.

Re: Intermittent turn signal (IrishFan)
I have exactly the same problem. Happens on and off with no rhyme or reason. Goes away just as mysteriously. Both signals. Just plain dark and dead.
This was a hint from c4c5specialist: "It is most likely your emergency flasher switch."
Try this the next time it happens: push the emergency flasher switch in, then out.
Turn signals should work again. Let us know, for the "database" that this came out of.
You can replace the emergency flasher switch, but it's a couple of hundred dollars, according to the dealer.

Re: Intermittent turn signal (IrishFan)
I have a similar issue but it is with my RH signal only. Previously it was erratic but now it is all the time. My rear lights are fine and I have changed the bulb up front.
Someone has the answer here. We have had several threads on this and there is nothing definitive yet. Given that the whole dash has to come out to RR the hazard switch I would like to know before we start just swapping parts and hoping. We need input from someone who has nailed diagnosing these things and then we can make it a Tech Tip so this issue goes away. Thanks all.

Re: Intermittent turn signal (pinot)
I have an 04 Z06, when it was one week old the r/f turn signal did not work & the system flashed fast. Parked in my garage tried it again same results, shut engine & left the car. Next morning it worked fine, no problem since in almost 3 months. Go figure.

My input came as a result of a conversation with c4c5specialist, who has made a reputation and living nailing and diagnosing these things.
The specific symptons listed by IrishFan were:
1. Intermittent (20%)
2. Both signals
3. Return to normal operation without intervention
Both builtfspd2 and I pointed to the emergency flasher switch. I have verified this, so has builtfspd2. So has c4c5specialist.
For me, that's pretty "definitive," especially since I've now used that solution about five or six times in the last five or six months, and it works every single time. Instantly.
You're input on the cost of replacing the switch confirmed the quote from the dealership. Pushing the flasher switch in and out the next time this occurs is a free diagnosis and fix for IrishFan. It could also be one for you, although you're symptons are somewhat different, e.g., one signal only, and all the time. Let us know when you've tried it.
Cheers. :cheers:

Re: Intermittent turn signal (IrishFan)
I had the same problem with my 2000. It is the hazard switch which causes this problem, $35.00 from the dealer or cheaper online.
I removed the kick plates below the steering column so I could reach my hand up to the hazard switch. I also had my radio out because I was replacing the A/C display.
I then removed the cover on the hazard switch, the one with the orange triangle by prying it off carefully. The hazard switch has two tabs that hold it in place. I first tried to lift both at the same time but there is very little room. So I put a flat blade screwdriver on the front of the old unit and hit the back with the palm of my hand. It popped out the first hit and I snaked the unit and wires down. Took less than an hour total time and everthing works fine.

in about 80% of c5's it's the turn signal flasher
In about 80% of the C5s, it's the emergency (hazard) switch.
Not that the above posts are a statistical sample, but that's the case. :smash:

Re: Intermittent turn signal (Dan_the_C5_Man)
Thanks for all the input; you guys rock!
I'll give the hazard switch a try next time this happens and will report back on my findings.

Re: Intermittent turn signal (IrishFan)
Definitely your hazard switch. My car had that behavior immediately after I purchased it. My extended warranty wasn't in effect yet, but the dealer replaced it no cost because it was a safety issue (and was within 10 days of purchase, when I got my '00 back in Feb.).

Re: Intermittent turn signal (Sorny)
Well, I'm pretty frustrtated. :cuss
I drove around the city for 60 miles this weekend and not a single event; the turn signal worked every single time. Grrrrr...
I'll give it another try next weekend...

Re: Intermittent turn signal (Mel 2001)
Had both turn signal and hazard switch replaced on my 2000 FRC under warranty at 35,400 miles-- I think their is a TSB out on this- You might check with dealer.
