Not sure about the 5.2 but on the 4.0 the small black plastic line to that T goes through the firewall by one of the aluminum AC evaporator tubes as ZeeJay already mentioned. You may have to fish around a little in the foam around the tubes and hopefully it didn't fall all the way in. That line is the feed for the vacuum switch which controls where the air flows from the ducts.

Do you have an under-hood light for the engine compartment? If not that might be the plug to it and look at the below photo of the plug along with my 5th post.

Plug may be for the coolant level sensor.

A picture would be a big help here. I cant figure out what exactly you are describing .

Good point coralman and w/a limited you probably have a coolant level sensor. We just had a discussion about this and if you have a Limited/VIC there's most likely a windshield washer fluid level sensor. Since mine's a Laredo w/o VIC (lucky me, lol) there's no float/sensor in the windshield washer fluid reservoir or the coolant reservoir. Wouldn't doubt I may have a small 2-prong plug laying around the coolant reservoir with nothing it connects to since there's no sensor.

So the vacuum line is fixed and all is well with the blower motor control. And the loose connection was originally for a coolant level sensor, but the coolant system was upgraded years ago (before i got the car) and the connection is now just a dinosaur. I capped it off. Thanks for all the help.

Well, I wouldn't mind having a VIC if I knew how to fix it if it started acting up. Sounds like you do coralman if you were able to wire one in yourself.

Glad your problems are figured out/solved. Sometimes I'll run across a rogue connector which must have been for an option I don't have and as long as things are working fine I tend to ignore it. But not a bad idea to figure out what it's for.

Hi guys I'v got a similar problem with my 2004 4.0 TJ, on the left side there is a vacuum line that is loose, it is supposed to go to a small box on the left side (will post a picture later) but think the last owner just closed both ends, now cruise-control isn't working, you think this might be the problem? A/C works fine.

This is my first Jeep (95 Grand Cherokee Orvis edition, 5.2 V8) and it has a few projects ahead for me. However this thread discused both vacum and empty electric connections so I thought Id ask...........

There is a large black hose coming directly off of the passenger side of the manifold that is plugged. Im sure it needs to go someplace and I have a number of issues it might effect.

Also there is a large plug coming out of the wire harnes along the firewall on the passenger side as well.

Tried to show both in the attached photos. Any thoughts on where these need to go?

Thanks

Revisted this thread, as I often do others when I just can't stand to watch one more wonder drug commercial on TV. I suppose it will eventually get to the point one pill will do it all, low chloesterol, lower blood pressure, toe nail cure, keep your junk up, depression supplements to your depression meds, depression meds, and the damn commercial will be 4 hours long. Geesh. Anyways, I'm thinking of modifying a brake line or some metal tube to take the place of the vac line through the firewall. In the next few weeks the climate control housing is coming out anyway to be reworked.Maybe a sleeve of some sorts. Of course I may just say say to heck with it cause the side effects list is too long.

the elbow is broken off the PCV on the valve cover . i think the hose would go there.

Coralman, can you imagine how fast the "fast talking disclaimer guy" would need to talk at the end of the commercial?

Here's to you mr. fact talking disclaimer guy.
