The switch is good since I tried it with mouth air before when I thougth it was broken!

But do you mean that a leak could cause vacum to activate the switch?
I thuoght a leak would make the light not to light!?

4WD light always on after connecting lines to transfer case

Hi again.

(Sorry forgot model; 1989, YJ 2.5i with manual gearb.)

I actully had two question, but I have been around before. Asking two question in one thread never gives you both answers

My clutch release bearing went last week. (I have manual gearbox)
So I had to purchase a new one (Expensive in Sweden) and then I followed the Haynes. Removed transfer case and gearbox. I suddenly noticed that the big connector with the vacumed lines where laying beside and not connected. I have never had the 4WD light ON, when I shifted into 4WD, but I am 99.5% sure I HAD 4WD atleast.
Now as I saw this I thought that it just had jumped out. After the bearing replacement I put the connector ON the transfer case and finalized the mounting.
The clutch worked ;Great!!!!!
BUT, now my 4WD light is always lighting!!!!!
I still THINK that when the 4wd stick is not in 4wd mode, I dont have it and when I put it in 4WD I HAVE 4WD, but I dont get it.

Does anyone know what could be wrong.
What I did notice when driving 2wd is that when I go up a hill and have a high gear and give some throttle, then it goes out for some seconds. Surely has to do with the vacume!?!?!!? but it always lights back on when releasing some throttle.

I also dont get how the 4wd works.
What does the transfer case do and what does the vacum bell do on the front axle????

Would really apreciate any comments!
