I bought a 99 xj 4.0 6cyl. for 500 bucks. I have read other threads bout the defrost and cruise. There is a hose and no cracks anywhere i can see. I will post pics. There is also a hose coming up from underneath but it not hooked to anything. Sry if j have done something wrong or if i asked a stupid question. This is my first jeep/4x4.

 

Sorry forgot to get the pic of the random hose. Take one tom. Thanks in advance for any help.

 

Look on the passenger side, behind your front bumper. Is there a round black ball where that hose hooks into? If not then you are missing your "jeep egg", and need to go grab one from a jy.

 

Check the vacuum hose that connects to the vacuum ball behind the passenger's side front bumper. It runs beneath the battery to the bumper. This hose was the culprit when I had cruise/defrost issues and replacing this one hose solved both problems. Your vacuum ball could be cracked if your hose is ok. Good luck!

 

From looking thrubthe top it looks like its there. I will go out now to look. I will also upload another pic of that hose that isnt hook to the motor. Are all three vac male inserts on the mani suppsed to have hoses to them?

 

I looked under there and the ball is there and those is hooked to the hose that goes into the t. Is there anythongs else hook to it that i didnt see. sorry for all tje questions. running defrost probably dont help my mpgs.

 

Anyone now if that hose goes on to the mani for vac look like it goes down to.the front axel area.

 

is that a hole in the line

 

breather hose for front axle looks like

 

there should be a hose in and out

 

So it doesnt go to anything?

 

Thats a good question I will do a better inspection tomorrow supposed to be in the 40 lol. I also will pull the cover off and look at the ball a little better. It was only in the 20s so didnt stay outside to long.

 

Is there supposed to be a vac line hook in that one. There is just a cover over it now.

 

Well i think i have figure vac leak i dont think the clear house fits right so I am going to replace it. But what bout the third male vac spot on the mani.
