To start, wow.. what a great site.. Found it a while back when I was looking up some information on my older 91 Grand Prix SE. Due to horrible up keep (before I got it) and some major problems I gave up on it, but was lucky enough to find a 1997 Grand Prix GTP via private sale with a little over 60,000 miles on it in great shape and was treated very well (soon to be treated better though )
Anyway, not much of a automotive person and having a odd problem. Started with what I thought might be a leak in the washer fluid reservoir. Couldnt track it down, no cracks and no leaks in hoses. Asked a great friend (much more automotive knowledged) to take a look at it since I only got it a few weeks ago.
Strange thing is, pump pushes fluid when reservoir is refilled to max and stops when it reaches emptyer state (about 50% full). While trying to track it down we both noticed the vacuum line going to the resorvoir and were curious what it was for. Anyway, filled resorvoir and started car and watched vacuum actually pull some washer fluid in :shock: . My friend has never seen the vacuum line going to a reservoir in other Grand Prix's.
A family member has a 1997 Grand Prix GT and I dont remember seeing this in her vehicle but will check tommorow if I can see her vehicle in the day.
Does anyone know what this vacuum line is for? And possibly why I am seeing tis strange problem?
