Cadillac Repair/Cadillac sls


My 98 SLS has a winning noise that don't get louder it sounds like the power steering but its not iv checked every thing but that's where the winning is coming from


Then the problem has to be internal in the steering rack. Noises are real best left up to a technician that can hear them and if it is as you say, the answer would most likely be the same and just to hear it, you shouldn't be charged.

Someone's description of a noise to diagnose over the internet is impossible to do.
You could have a bad power steering rack cavitating (sucking air internally). You did not say if it was louder when turning.
Could the noise be coming from the passenger side of the vehicle and it changes with heater blower speeds? A bad heater blower or squirrel cage could be the issue.

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
