I am hearing a hissing and gurgling sound from under my glove box when I park my burb after running the a/c. seems to be blowing as cold as ever, but I don't remember it being this noticable last summer. is this normal or is something going wrong.

I have the same sound. I was told this is the it has somthing to do with the refridgerant moving somewhere...

does this mean that it is harmless, or does it need attention ?

My burban runs fine, with no problem and it has done it for a year...
