Question
Hello Rob,
Thanks for your reply of 5th December re above.
Firstly, an aftermarket kit is available from Strutmaster.com for $299 plus shipping etc.
I used my car today and when I returned to it I noticed that now the rear end is much higher than the front(about 1 inch) instead of the rear previously being lower.
So can I assume by this that the compressor is working fine and that there are no air leaks, as the compressor has obviously now pumped the system up(although it is now too high!!) The "Service CCR System" light also came on again ( this is also the first time the Service CCR warning has come on in a few days).
Would you say the problem is more likely to be a sensor or a computer problem and is it relatively easy for a mechanic to check??
Many thanks
Andy
Hi,
Glad you found out about the after market Strut master in the UK.
As far as your leveling issue now, this could be either a sensor on the rear axle or maybe even a problem in the body control module (BCM).
Have the sensor checked and also see if there are any diagnostic codes in the computer.
I have always had issues with these ride control units. They are plagued with problems. Yours is a great example. First its too low, then its too high. Compressors fail, commonly when defective, ignition switched power is replaced with constant battery power run the battery down. Shocks leak, sensors fail and the list goes on.
Personally a set of good springs or struts are the best way to go. The less working parts, the better.
Good Luck!

| Comment | Thanks Rob for a very quick response-I will have sensor checked next week but I may just do as you advise and replace with basis struts/springs to avoid any future problems!! Many thanks for excellent advice Andy | ||

Expertise
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?
