oops...hit the wrong button-sorry-carefully pry the unit up and then
once off you'll have to improvise an alternative method of re-
mounting the light. Example would be the proper sized nut-glued into
the old spot! Good luck JP

Jerry,

Thanks for the direction. It doesn't seem like it will be a cinch to pry
this thing up but I'll give it my best shot. What a PITA this has turned
out to be. There must be a reason all the other models have the light on
the roof itself rather than the glass...

Andrew.

Btw.. I have a super-stupid q for you if you're in the mood. The vac check
valve on the vac reservoir under the hood - which way does it operate? I
feel like I've had a dose of stupidity - I assume it should let air into the
'ball' to keep positive pressure but not allow it back out??

Hmmm, thats kind of a brain teaser Seams you would not want a check
valve right at the resevoir because the vacuum/air needs to go both
directions.

But, at something like the brake booster you want it to go out so it keeps
vacuum at its highest. even when the car if shut off.

Thanks again Steve! I guess I'll see when the new part arrives. I bought
an OEM replacement with a built in check valve. I will go try to hunt the
one behind the dist down for testing. I can't find a diagram anywhere that
references the check valve location/s... MOD, Chiltons, Haynes... Nada.

Take care,
Andrew.

On the 95 the valve should be in the line coming off the back of the
manifold. If someone has changed the lines in the past they may have
moved it farther out from the manifold but it is usually easy to find,
just look for a white plastic item the shape of a small fuel filter.

Steve,

When you say manifold are you actually referring to the plenum/intake hose
that goes by the distributor? Mine has no such white fuel-filter looking
thing attached to it but it cetainly doesn't look like it was ever replaced
either.

I have a straight PCV valve that should act as a decent check valve. I will
put it in line with this hose and see if my surging issues fade away in the
meantime before I replace the vac reservoir.

Thanks.
Andrew.

Take a look at the third picture on this AZ guide.
http://snipurl.com/1txg3
It is the 2.2 but it shows the vac ball better than the rest. If you
look just to the right of the brake booster you will see the check
valve. On the 4.3 it is usually closer to the engine. The next picture
shows it but not real clear, just to the right of the number 1 tag.

Steve - now I think I know where you're talking about. It comes directly
out of the manifold and looks almost exactly like a PCV valve with a hard
line that goes directly to the intake?? I didn't think this line went to
the vac ball at all but perhaps that's exactly the point. I didn't realize
that the tee there was a check valve.
Thanks!
Andrew.

Took a couple pics of a customers 97. The lines should be close to a 95.
http://snipurl.com/1tywc

The blue line is ported vacuum. The green circled item is the check
valve. The lines in orange are all connected to the ball through the T
on the valve. If you look at the orange circle you will find another T
that splits the line again. The lower right goes into the interior for
the heat/AC control. The orange line going back across goes to the 4X4
system through the control valve on the transfer case.

Steve,

Thanks a million this is the info I needed for sure! The vac routing is
identical to mine. The funny thing is that I can't find a listing for that
damn OEM check valve anywhere. I'm sure any 3/16" check valve would work
though...

Take care,
Andrew.

Well since just about every maker uses a similar valve the bone yards
should have a LOT of them. I've probably got 20 of them laying around.
The come in handy for a lot of stuff. If you want a new one I have seen
them on the Motormite/HELP racks in parts stores.
