Turn signals blink slowly when '06 CTS 2.8L is running but work correctly when engine is not running. Any solutions?

Of course when the engine isn't running and the blinkers are flashing faster, you have the key in the on position. Correct?

How is the four way blinker? Do the exhibit the same thing with the engine running compared to it off? Also which speed seems more normal to you? The engine off or the engine on?

Sometimes when you get a slow blink, one of the bulbs may be blown.

I thought if a bulb was blown it would blinker faster, twice as normal.

 

[Coma]

yes, blown bulb makes them blink faster. never hear of a slower blink... >.<

Back in the day, I had an old Oldsmobile. When a bulb died, they would blink slow. That was in the 80s, I'm sure the circuit is different on current cars.

When the key in "on" but engine not running both the left & right turn signals and the four-way's work properly. All bulbs are working. Engine running, headlights "on" turn signals operate significantly slower than with key "on", engine off. C
