Does anyone have an idea what is causing my air pump relay to blow every 3 to 6 months? (the one under driver seat on chassis frame) Have replaced it 5 times since I owned it, less than 2 years. I have a 2008 trailblazer L6. I have used NAPA brand, Omni brand, GM brand, makes no difference. Thanks for any help.

My guess would be that the pump is drawing too much current and causing early failure of relay.
