Need some expert advice here. Purchased a '94 DeVille (with the SSS system) from the son of the original owner (38k miles). "SERVICE RIDE CONTROL" message is on the dash. Took car to the local Cadillac dealer and was told it would be one hour labor to diagnose; figured it was one of the struts and at least one pair of struts would need replacing. After one hour, I was told that none of the struts was receiving a signal and they would need more shop time (1 or 2 more hours) to examine the wiring to determine the cause, as there seemed to be a dead short. They said they would start at the fuses and relays and work from there. I went ahead and approved the additional time. After two more hours, I was told that the wiring was fine and now they were looking at two control modules and the wiring between them (I'll get to another point later, but I am after-the-fact guessing they were referring to the SSS module and the PCM). After another 1.5 hours I was told the car needed a new "Body Control Module", which they would have to order. I asked what the bill was so far and was presented with 4.5 hours that was $20 per hour HIGHER than the shop rate I had been quoted when I made the service appointment two weeks earlier. Oops, someone must have given me an incorrect rate...I told them to close out my bill and give me a detailed estimate on their recommended repairs with a list of needed parts, part numbers and prices. Kind of felt like I was financing the education on the Cadillac SSS for his service technician and I still did not have a great deal of confidence in his diagnosis. I was told by the guy in the parts department a price for the "needed parts", but "I didn't need the part numbers because they knew which ones to order and would get them when I made another appointment to have the rest of the work done".
Long story short, I referred back to the factory shop manual and could find no "Body Control Module" for a '94 DeVille with SSS. Called back the service writer at my local Cadillac dealer and, after consultation with the service tech, now decided it was the PCM that my car needed. OK, now that's at least a part this car has!
Fast forward to yesterday. Had a reason to call the owner's son and he said the car was taken to their dealer for diagnosis of the same thing before I bought it. He said his dealer had told him whatever was defective was no longer available from GM and the cure was this bypass harness that GM sells. Called that dealer this morning, but no notation was made on the work order except "Check and Advise", but no mention was made as to what the advisement was. This was only about six weeks ago, so I asked to have the tech or writer who handled the car to give me a call back; I'm hoping maybe they remember what they found out when they inspected the car in late October.
Does any of this sound plausible? HELP!!!!!
