Hi there, I read the what the code explanation is in the DIY section but does anyone have any step by step instructions how to replace the air pump, hose & air check valve....how diffilcult is it to replace the relay if that is the part thats broken? Gonna check to see if the fuse has popped tomorrow and the relay this weekend...any info. will be appreciated

As far as replacing the relay, just pull it out and push the new one in.

The pump is located under the radiator. If you take a look at it, it is fairly straight forward as far as removal. The intake tube should be clamped to the side of the fan shroud on the passenger side about half way up. I have posted pictures of how it looks in at least one other thread.
