It's an intermittent problem on an'05 V8 AWD. Most of the time they work fine, anybody else have this problem?

I also experienced this on my 04. Went to use the turn signals, and nothing. Then a few minutes later, everything back to normal. The first time is was raining, but the next time it was dry. Is there a TSB on this?

I experienced this driving my '04 CTS through the mountains of West Virginia during a rainstorm a couple months ago. They just quit working. Then started working again just as suddenly. No problems since.

BTW, how did you know the turn signal was not working. Was there an alert or just the indicator on the dash wasn't blinking?

I used the turn signal like everyone does, but nothing happened. Tried the other direction, nothing. Then a few minutes later they are working again. Hope I never get pulled over for not using my turn signals and try explaining that!
