Cadillac Repair/air shocks

Question
QUESTION: I have a 99 Eldorado and air shocks won't air up when passengers ride in back seat. Can hear pimp running. Car Aires up fine with no weight. Any suggestions?

ANSWER: Hello,

It sounds like you have leakage in the rear shocks, or an air line. Something like this would be easy to check out if you can get under the vehicle with passengers in the rear. Take some detergent and water and a way of dispersing it, either with a brush or a spray bottle. Put the detergent on the shocks, the fittings and if you have to, follow the lines to the compressor. You will see the leak when bubbles grow.
By doing this, you will find the parts that need replaced and you can take care of the problem accordingly. If you are real lucky, you might find a loose fitting.

Good luck!

QUESTION: what would cause the stability to engage while driving? Mostly occurs when taking right hand curves. Could this just be a sensor or bad strut? Same car 99 Eldorado

Answer
Hello,

I am very good at all types of Cadillac issues, but I also know my limitations and do not want to give you the wrong answer on something I am not familiar with. I am sorry, I cannot answer this question with any certainty.

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?
