I can get my rig to raise and lower but sometimes it feels as if its not "perfectly" balanced and the fault is thrown within a min. of adjustment and the compressor runs a very long time. The dealer told me the compressor is "bad", so I asked if it was a height sensor or something else that was causing the Fault and they told me if that were the case the diagnostic would show that. I go in on monday for the new comp. and I bet they will find something else. I did verify through an electrician friend of mine that a compressor can be weak and still work,but I want to TRUST my LR and be confident that its up to par. FWIW, I could be overly cautious but get your rig checked out. At least then you will know what youre up against. What do you think the odds of the dealer giving me the old compressor so I can get the rebuild kit and travel with a spare?
