SOURCE: Error Codes
These may have been set by the battery change and are what GM calls phamtom codes, clear the codes with the following.
Try this and see if the codes go away.
1. Re-enter diagnostics via the climate control panel and after all the codes appear you will see .7.0
2. Simultaneously push and hold the OFF and HI (^) buttons on the climate control panel until you see E.0.0 and release both buttons.
3. Turn ignition key OFF, Wait 15 seconds and re-enter diagnostics and see if the codes reappear. If they do NOT reappear, You are good to go.
After you have done this try starting the engine and see what codes re-appear, also run and OBD 2 test of the system at the diagnostic connector, this will give P codes that we are better able to find definitions for, the E codes are unique to just a few GM cars.

Sounds like you have a problem with the pressure switches on the ac system. Find the aluminum lines for the ac, attached to the lines are two pressure switches plugged in to the car wiring harness. Make sure the sensors are tight into the fittings on the lines. If they are unplug them one at a time and bridge the two terminals in the plug going to the car's harness not the switch, with a jumper wire or cotter pin which ever wire turns on the ac compressor remove that switch and take it in to the auto parts store and get another one.
hope this helps you out

Hello, You probably have failed (broken) wire(s) coming from the ignition lock cylinder to the security system. To repair you need to replace the ignition lock cylinder, a new key with the same resistor. no programming required. Hope this helps
