well, finally got it to the mechanic a week or so ago. was hoping it was the pump...just because its under warranty...was just replaced in August. It wasn't the pump...it was the resevoir which had a crack in it. unfortunately though, I had to replace the new pump because there was no resevoir to buy seperately for this pump...unless I took the time to track one down in the junk yard. so bam..$230 instead of $110 for just labor. SUCKS! don't know why the resevoir cracked...it happened on one of those days when we had -40 windchill so maybe that's why. don't know. but it's fixed, for now, again.
