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

1988 Cadillac Deville. ELC light stays on in dash and drains battery


The light is on because the system fuse was removed, this causes the control module to see a fault. either fix the system or pull the dash and remove the warning bulb.

I have a 2003 cadillac deville north star. My car wouldn't start,we were told it was fuel pump.we replaced fuel pump still wouldn't work.checked fuses and now no lights,no dashboard lights come on.


Is the battery fully charged? You may have a power supply issue to the ignition switch or possible ignition switch issue. If battery ok... try jiggling ignition switch slightly to see if dash light come on. Are the dash lights the only lights not working or is all electrical out? Was the vehicle given a boost by any chance?

2002 Cadillac Escalade 4x4 When turning front wheels pop like in 4 wheel drive. Now the service stability system light is on full time also the ABS light. I have had it at two dealers one couldn't figure...


If you think the dealer caused it get a hold of GM district rep .Talk to the service manager . If the dealer Technician's can't fix it , get the factory involved . In most cases if it is something they did they need to take care of it ,free .

Car is acting weird,light on the dash board went black,gauges spinning


Your case could be the voltage regulator, when they go bad, the dash board goes into a light show, you will have to get the alternator out and checked, and probably replaced. But, you are not alone, if it isn't the regulator, it is the car, they have had a ton of complaints about the dash board lighting up with warnings and trouble codes and nothing is wrong with the car, It takes a rocket scientist to figure t out, because the dealer will take the car, fix it for 10 mins, then they come back on, and you get tired of taking it to the dealer. Get the code read while you are at it and see what it says. Hope this helps.
