it is part of the vacuum system. without it you dont have any AC vents it all blows thru the defrosters

 

vacuum canister

 

i learned yesterday you need it if you want your vents to work.

thats my bumper on the ground after we carried back.

 

It also runs your cruise control.

 

Are you guys sure about the no cent thing. I removed my bumper and that ball was disconnected but my vents still work. So does my cruise. I couldn't find the other end of the line so I guess it could be plugged or re routed. Just saying

 

i just read a thread that verified the no cruise thing. and i still dont have my canister connected(it has a hole it in) and i just went out and checked and i have no vents only the defrost vents work on every setting.

 

ok i will get a other one i just got this jeep and im still finding **** wrong it costing more and more damn it

 

You can hook it back up if its disconnected. Or move it into the engine bay. I always plan on spending twice as much whenever I do anything to mine. lol

 

Vacuum reservoir for A/C and cruise control, etc. You can get another in any junk yard. It does not have to be the same size or shape and you can relocate it anywhere in the engine compartment. The new canister does not even have to come from a Jeep!

 

I would hook it up in a heart beat but it broken lol trust me i would love too

 

ya my vents didnt work and only went out defrosters then i saw behind the battery one of the hoses coming from the canister was cut so i fixed it and they all work ,but my steering column is messed up so my electronics dont work so i cant enjoy it now

 

I have a 96 XJ and when my line got a hole in it my vents and cruise would not work. I fixed the line and all was well again.

 

Defrost is the default mode if there is a vacuum leak in the system.

 

I think you can just cap off the hose to reseal the vacuum and it will let the vents work again, no vac tube necessary.
