    air pump relay blows

    Is it possible to walk me through how to check the relay? Also, I had the exact same issues on my 2007 trailblazer for many years before I sold it.

    So even though it sounds like a fan clutch roar to me, it is probably the left wheel hub??

    I have a 08 trailblazer, 4.2L 6. Upon driving I hear a very loud roar, that is speed related. When slowing and braking the noise "winds" down accordingly. I have replaced the fan clutch, and the emissions valves, solenoids, and air pump are all functioning as they should. I seem to notice...
