Re: 2004 Blazer 4x4 Issues
Yes.
If it is a flash flash and pause and then flash flash it is code 2.
But a flash then pause and flash it is code 1 repeating itself.
Code 2 is encoder motor or circuits.
If you have the book check the circuits and if they are OK replace encoder motor.
Also clear code and see if it returns.
Sometimes a battery disconnect will bring it back on line.
Good Luck
