AIR System

MY SES light came on the other day, I pulled the code that came up AIR System. I check the AIR pump fuses under the battery. The Big 30amp fuse has power in and out but there is no power to the little 10amp fuse, It is not blown though, also no power to the air pump at all, all of this is during idle. On the block with the fuses is a relay, could that be the problem. The SES light does not go off even after disconnecting the battery for 10 Minutes. Checked the power wires with a DC Voltmeter to see if there was any power. Can anyone help?

you need a scan tool to reset the light. what happens is water gets in the pump and locks it up then the maxi fuse blows. most of the time you need to replace the pump but sometimes you can remove the rubber inlet hoses and dry everything out with compressed air and it'll work again.
good luck
