I have replaced the left blinker BULB in a C5 and it still blinks very fast. RIGHT BLINKER blinks as normal speed. Both are new bulbs. ANY IDEAS!!?????? PLEASE HELP ASAP!

Check the bulbs on both the front and rear on the right side. A bulb out in either location will cause that side to blink faster. Check both rears one also If all the bulbs are good, then it is the flasher unit. A little more expensive, but not too bad and easily changeable.

Or turning signal additive was not used with it. Turning additive increases responsiveness 23.8% and brightness 2 times. Do not change your blinker fluid without adding turning additive. Just not worth not using it IMO.

And only use the GM turn signal additive. The parts store junk will cause radio interference and make your GPS give you bad directions.

Definately some sig worth comments in this thread. Had me rolling.

Gotta love the smell of blinker fluid when it comes up to operating temperature. Reminds me of Napalm.

Plus your dealer will void your power train warranty if they find out you have been using non GM turn signal additive. That is just a chance I am not willing to take, so the few extra dollars is totally worth. Most dealers do have a display that shows how turn signal fluid preforms by its self and with GM turn signal additive. Just ask them and they will be more than happy to show you it.
