Hi, i have an 08 ford 5.4 f150.

i found a plastic hose that broke off from the driver side that goes to the iwe on the driver side. i'm just wondering where that connects. the hose comes up under the air duct. one of the line is not broken, i believe this is the breather or vent tube that runs across from one end (solenoid) to the other side of the driver. the piece that i believe is broken is the vacuum line that goes to the iwe on the driver side. i just need to know how or what supplies vacuum or where it connects to on the driver side. I've attached a picture.

 

Refer to post #3 in the other thread that you posted in.

 

 

That post has a vacuum block diagram for the IWE system.

 

so according to the diagram, that one end on the driver side should be open. like it's normal for it to be like that?
how come i'm not getting any vacuum from the driver side when i take off the hose? where else should i check?

thanks.

 

There are 2 lines on each IWE. One is a vent tube, the other goes to the solenoid. You will only have vacuum when the engine is running and it's in 2wd.

Read that other thread from the beginning. The first 2 posts give you detailed troubleshooting.
