Anyone know how to fix hyper flash on 07 ss? Tried resistors with no luck. Any ideas would be greatly appreciated

 

Find @The_Maniac here and see if his modded flasher will work.

 

The 06-07 Monte uses a different Flasher Module than the 00-05. I never looked into the 06-07, but I believe the chip found in the 00-05 flasher modules is pretty common with other modern flasher modules. If it is of any help, below is the link to the process to mod the 00-05 Flasher. Welcome to see if that helps:

I looked in Impala forums and the sad news is that the flasher is controlled by the BCM. Might be better searching there since I think the Impala is the most common W body of that vintage.
