I have been recently getting a c1130 code - my 06 RRS 4.4 sits level overnight and the compressor only runs for the first few minutes of me starting the car.
I traced a leak on the top of my front passenger strut (it would make a horrid squeal when hitting bumps, but that stopped when i tightened the 12mm airline nut).
I pulled the part number of my front strut and it says RNB500223. Are there any other RRS/LR3 model struts that would work - such as RNB501620?
Or is the C1130 another issue - like the front valve block (have a spare sitting in the garage).
