Right signal light flashes fast, left signal flashes normal speed?



Fast blinking means you have a bulb out on that side. :th_winking:
 


No, but that is understandable, had a '90 caddy and it didn't do it, and a '92 cavalier, and then a 98 truck.. None of them had that feature, it sure is handy though :D
 


There is a flasher module on many cars that allows current to flow through a peice of "special metal" that gets hot as current flows through it. When it gets warm it expands. Once it hits a certain temp, it will expand enough so that it breaks the circuit. When a bulb goes out, it changes the amount of current going through the circuit and the expansion/heating rate changes as well.

Positive side of circuit o--------o "special" wire expands upwards
Negative side of circuit o----*
 
The 5-button DICs on the 04+ will for example if you right rear turn signal is out a message will show up that says "Right rear turnlamp out." It will only come up once then the blinker will blink fast.
 
I had the same problem and DIC indication but problem persists even though I replaced the bad bulb, rear right on '06 standard model.
Any ideas anyone ?
 
really? I have known cars to flash fast or stay lit when a light is out for years and years. it is one of my pet peeves to see someone with the front flashing like crazy and the rear nothing. I wonder what that person is thinking? anyway, I realize not everyone knows of that feature
