This is Kurt. Do you have an answer on my codes

Hi Kurt. These codes are for the hybrid control module and motor. You did not know if you have a hybrid or not.

I asked you to verify the codes for me but you said your wife was out with the car. Is she back yet??

No l will get back to you

ok, I was just checking and also found out that if you do have a hybrid, it is covered for 8 years, 100k warranty. that would mean it is covered under factory warranty.

roy don't know how to send picture to you but codes are right

Ok, then you have a hybrid system in your car. You do not want to mess with this system, it is very high voltage and if you touch the wrong wiring you could get severely hurt.

besides it is under warranty. call you local GM dealer and take to them for warranty repair.
