This tells you how to get the stored codes from your PCM. Post your codes and someone will try to help. :chevy

 

On my '98 it was a steering wheel position sensor. Once replaced, no more code. :chevy

 

found some codes, maybe one causing problem:
10-pcm-p1433h

28-tcs-c1255h
c1281h
99-hvac-b0361h
b0363h
b0441hc
