2003 GMC Yukon V8 All Wheel Drive Automatic 84000 miles
My autoride suspension compressor on my 03 yukon xl denali isn't working. The dealership stated I need to replace it. However, the tech mentioned that he believed that the exhaust valve? Was likely dirty or had debris in it - and that I could clear it myself (he couldn't do it for me as per their 'policy'). I have taken off the rubber shroud from around the compressor. What do I do next? Is there a tech drawing on this available? Is it easy to do?
