Hello Everyone,
Recently, the 'Engine' light on my 1980 Buick Lesabre has come on. It only comes on when the key is turned on. It does not stay on while the engine is running. I have been trying to figure out how to extract the engine problem codes. I have a Haynes manual that discusses how to use the ALDL Connector to extract the codes. After much searching, I am not able to find this ALDL Connector. I did some research online, and came across a 1980 El Camino driver, who noted that his car does not have an ALDL Connector! So maybe this is something that was not available for older GM cars? If someone has done this before, I would greatly appreciate the steps to extract my engine problem codes! Thank you very much.
