My SES light is on and I am pretty sure it is the air pump...used to hear it come on so when I didn't hear it the other day I checked the fuse and it was blown. I took the air pump out and there was water in it, so I drained it, changed the fuse and it worked...However the other morning it once again did not turn on, so I checked the fuse and it was fine, but exhaust was coming out of the airpump intake...is the air control valve busted? how can i fix this or atleast where should I start?
