Another compressor problem

[Scott Forman]

If you have an air dryer, check the relief valve, sometimes they stick
open. Often of you cover the outlet on the bottom with the palm of
your hand with the engine running, it will fix itself for that trip.
If you find this happening, you need new relief valve.
