      I assume that you mean that the starter does not even operate? No crank when the key is turned? Is there a SECURITY light on while cranking?

    Can not remove key from the starter. Vehicle appear to be in the ON mode because there arelight on in the dash.
    the light are out on the radio/CD player/ air conditioner/heating system. Car will start but can not change the gear. Keys wont come out of starter.

      I am almost certain that this is a warranty issue. Call Cadillac. Cadillac dealers have some latitude to the tune of about 2 years beyond the stated warranty to "goodwill" many repairs. Call them. You did not hear that from me. I believe that you will need a new shifter ass'y, known issue.

      Power to the PCM may be disconnected by removing the PCM fuse in the fuse box, disconnecting the in-line fuse holder near the positive battery terminal or disconnecting the PCM power lead at the battery terminal. If you disconnect the negative battery terminal, you will lose other memory data.

      There is a chance they are connected because your ISC (Idle Speed Control) adjusts when you turn on your AC. Anywaym have you adjusted the minimum idle screw? One point here is to not disconnect the idle speed control motor or reconnect it with the ignition turned on or the engine running.

      Replace the low pressure temperature switch on back of compressor, thats might just do the trick.

      Since finding a manual for your classic car is quite hard to comeby

      Did you already perform the radiator and cap pressure test to verify or see if there is a visible leak in your cooling system? How about compression test? To know the condition of your engine, it is possible that your cylinder head gasket is failing due to excessive heat from overheating.

      You should consider performing a radiator flush to clean the inside of your radiator. Also check the condition of your radiator fins for any foreign objects that restrict the flow of air that help dissipate the heat in your coolant

    P0155 &p0135 O2 heater fault. Replaced sensors & still have same problem.
    I checked for voltage and groung at connectors. Both ok. I replaced sensors with OE sensors. I reset the check engine light and I got the same codes again.

      P0155 means oxygen sensor heater circuit malfunction (bank 2 sensor 1) and P0135 means oxygen sensor heater circuit malfunction (bank 1 sensor 1) the common causes of this trouble codes are short/open/high resistance in your wiring harness or harness connectors and defective oxygen sensor . Are you certain that you’ve replaced the oxygen sensors in your bank 1 sensor 1 and bank 2 sensor 1 and check its wiring/connections?

      Recheck the power and grounds. I can find nothing else to blame. Bad PCM is possible, but rare for this reason.
      G109 is a common ground for all HO2's. Inspect for a loose or missing ground at G109, located at the left rear end of the transmission, on a bracket stud, above the transmission bell housing. Test the OXY SEN 1 and 2 fuses and ignition power supply to the HO2's heaters.
      Should be battery voltage.

      What have you done so far to fix the problem with your vehicle? Did you already check the condition of your fuel pump and its relay? A faulty ECT (engine coolant temperature) sensor can also cause your vehicle’s trouble. Have you already diagnosed your vehicle with a scan tool to determine if there is a stored trouble code in your vehicle (if the fault is one of your electrical controls or sensors it will show in your trouble code, if you have any) that can help you find the fault on your vehicle’s problem? You can visit AutoZone or nearby auto parts store for free diagnostic.
