Question about 2004 GMC Yukon
Posted by Anonymous on
Many posts on this one. The small air compressor that adds air to your air shocks or "level ride system" is no longer working. You may have heard it turning on and running more frequently before it stopped working altogether. It is usually located in a protected pocket just behind the left rear wheel. Typical failure mode is due to an air leak in the system, causing the compressor to run more frequently, eventually overheating and seizing. May also fail due to a bad electrical connection caused by corrosion. Normally fails after your warranty runs out and can cost anywhere from $500.00 to a thousand, depending on many factors, including greedy dealers. The compressor itself may be fine, it may be a leak in the air line or the shock itself. Have a trusted mechanic check it out and for a reasonably priced replacement of either, go to http://www.arnottindustries.com/part_GMC_Air_Suspension_Parts_yid15_pid95.html as others with this problem have recommended on these forums. Good luck.
