  1. Disconnecting the battery will eventually delete most of the codes, but it will also set codes indicating the PCM has lost power. It is far better and quicker to delete the codes through the procedure previously described.
  2. The controls for the climate control are the same for either engine for the 1992-1994 Seville. I have marked the buttons with their functions. If you have an owner's manual, they are also in there. If you don't have one, there are several websites that you can download a digital copy, if you want one.
  3. Today I purchased a used radio head. That solved the issue. Apparently the old radio head failed immediately after the battery replacement. Looks like it was just a coincidence.
  4. Engine Control Module (ECM) Powertrain Control Module (PCM) Basically two different names for the car's computer system. They are often used interchangeably.
  5. EJJE This is how to access and clear codes on your Eldorado. No OBD scanner is needed. To Access Codes Switch ignition ON. Simultaneously press and hold the A/C control panel ‘OFF’ and ‘WARMER’ buttons . When all segments of the display illuminate: o Release the A/C control panel ‘OFF’ and ‘WARMER’ buttons. Trouble codes will be displayed on the driver information display. Trouble codes will be displayed in ascending order. NOTE: All ECM codes start with the letter ‘P’. Trouble codes for other systems may also be displayed. All current trouble codes end with the letter ‘C’. All history trouble codes end with the letter ‘H’. If no ECM trouble codes are stored, ‘NO E CODE’ or ‘NO P CODE’ will be displayed. NOTE: If ‘NO E DATA’ or ‘NO P DATA’ is displayed there is a communication problem between the ECM and the instrument panel. • When all trouble codes have been displayed: o Press the ‘AUTO’ or ‘DEFOG’ button or switch ignition OFF. Erasing Switch ignition ON . Simultaneously press and hold the A/C control panel ‘OFF’ and ‘WARMER’ buttons. When all segments of the display illuminate: o Release the A/C control panel ‘OFF’ and ‘WARMER’ buttons. • Trouble codes will be displayed on the driver information display. NOTE: Pressing and releasing the ‘LOW’ button will bypass trouble code display. • When all trouble codes have been displayed: o Press and release the ‘LOW’ button until ‘PCM’ is displayed. Press and release the ‘HI’ button. Press and release the ‘LOW’ button until ‘PCM CLEAR CODES’ is displayed. Press and release the ‘HI’ button. ‘PCM CODES CLEAR’ will be displayed for 3 seconds. Press the ‘AUTO’ or ‘DEFOG’ button or switch ignition OFF.
  6. I disconnected the battery for about a minute, as suggested by rockfangd. Then hooked it back up. While it is disconnected I touched the 2 cables together to discharge the system. Radio still no go. I also removed the radio head unit and removed and reseated the two connectors, to ensure that I had good connections. What are the next steps?
  7. I replaced the main battery a few days ago, the second time since I have owned this car. After replacing the battery, I expected to need to set the clock and radio presets and initially I was able to do so. I parked the car and turned everything off. When I went to use the car a few hours later, the radio/clock would not turn on. The clock shows -:-- on the display and if I turn the power switch on and back off, it will display the default radio station of 98.1 for a few seconds, but no sound. I have checked all of the fuses I can find. The mini fuse block on the left front engine compartment as well as the 2 MAXI panels next to it and the fuse block in the trunk. All fuses test out as good. I'm thinking that maybe a relay has gone bad? I have a shop manual wiring diagram that shows the RAP relay in the circuit, but doesn't give the location. Can anyone tell me where to find it? The ECM diagnostics shows a code of I052. I don't know if that is related to the radio issue, but it wasn't there before the radio stopped working and I am unable to find out what that code means. This car does use a 2 piece radio set with the control head in the dash and the rest in the trunk. It is the standard AM/FM Cassette (not Bose). There does not appear to be any anti-theft features on this radio (no LOC or Locked) on the display and I believe that this year didn't offer that feature. If anyone knows otherwise, let me know) Does anyone have any tips or suggestions as to how to get this working again? Thanks to all
