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.

SOURCE: 1998 cadillac deville still reads service ac system

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

I have 2000 cadillac deville and its overheating


P0741 - Torque converter clutch slip speed is exceeding limit; P1258 - High engine metal temperature. Sounds like you have transmission problems - torque converter problems can cause engine overloading, which in turn can cause the overheating. I would start with a complete transmission check before the engine is seriously damage the engine.

I have a Cadillac deville 1998 v8 northstar. I had my alternator rebuilt and got a new battery. Vehicle started once but dash read battery not charging. Took vehicle to O'Riellys Battery tested bad. H


When you replaced battery you activated the system. Need to read owner manual and see if it tells how to deactivate it. You may need to contact dealer to deactivate it.

Theft security problem


Usually it means the computer is not accepting the chip in your key.
It can be the key, the sensor in the lock cylinder, or something in the security module or computer.
You might try another key or lock and unlock the driver's door with the key.

Does a 92' cadillac sedan deville top out at 85 mph like it says on the speedometer?


Unless your car has a governor installed on it (doubtful) your car will do more than 85mph. At various time the government in its infinite wisdom has set limits on what the speedometer can read as a way to discourage drivers sppeding and from seeing what their car can do as far as top speed. I mean what's the point of burying the speedometer and holding it when you can no longer tell how fast you are really going.
