I got a 98 cherokee i just built a custom bumper for and i had a vacuum line hooked up to a plastic ball mounted to the back of my bumper. my buddy said it has something to do with cruise control is that true if so do i need it if not what do people usually do with it.

 

yeah it is used for your cruise, hvac system, etc. You can relocate it by the firewall by your master cylinder since the lines go to that area any ways.

 

Controls AC vent functions as well

 

Thanks for the input guys. Gonna relocate it this weekend. Nice easy modification. Im still a new member and have been finding awesome information about alot on here.

 

how is it used in the ac vents?

 

It's how the system divert airflow from vent to defrost to floor. Check my albums its easy to relocate.

 

Good one guy's, thanks. Mine has been hanging loose since the bailing wire broke. Didn't think of wiring it somewhere else.

K-nation, yea, the vacuum provides the power that moves the flaps.

 

The device you guys are referring to is called a vacuum collector. It holds vacuum so the various things like the vent deflector works when you change the direction of air flow, etc. All vehicles with vacuum controlled devices have them.

 

You never checked my albums? I'm disappointed.

 

Thanks, firearms, O...OK slick, I thought they where family photos..."Great Grandmaw Slick in her first fully blown Rambler" ect.

 

Lmao well grandma slick drove a 55 Chevy for a while. And a 62.

 

Would this also control the hot / cold mixture of the hvac system?

 

Don't think so. Think that's done with cables. Least mine didn't have problems with that when my ball leaked. Have any coolant smell in the cab?

 

???hvac system??? is different than my heater control valve which is controlled by vacuum?
