Hey guys,
I Removed a few things that had vacuum lines attached:
*A/c Compressor Delete.. Clutch seized so i took it out.. Windows work just as good for me. Also My vacuum line to Hvac Controls was dry rotted and broke at the firewall.
*Took out Cruise Control Unit and vacuum lines to that were also dry rotted.
*Vacuum Ball line was dry rotted as well
*I capped the vacuum port on intake that supplied vacuum to above components.

My question is will this cause any issues with other vacuum related components?? I would like to use the HVAC Controls atleast for heat in the winter but wiith the Vac Line broken at the firewall i cant really connect it to anything. Can i run a new line from from Controls to vac ball and to intake port??

Bump...

might affect the vents for heat and defrost

I knew you would be the first one after it sitting here for hours.. lol
What would affect it, changing the vacuum lines?
I think i can eliminate that ball anyways now that i started thinking about this again, if i run a signal vac line from the intake mani port that i capped off, and route it for my Hvac controls i wouldnt need the magic ball, would i? May not work when engine is off but i dont use a/c and heat that much anyways.. I would prefer to just use it as a softball and swing away.

Im pretty much going against factory setup. Removed useless crap and im toying with and re routing vac lines. Its all about the MPGs.... less stress/lil more power/Nice throttle response is what ive ended up with so far..

it stores vacuum so the control panel can keep the proper vent open with out it you will only have air coming out the defrost .and are you crazy no ac down here you must have big ones lol id die with out mine on those 99 degree days and 95 percent humidity and no breeze

All that means for me is hit the beach or pool and if im driving, go faster..

ok i get ya with the ball, that y i moved it there. But can i run a new vac line from the controls. All my lines that connected to the vac ball, Cruise and Hvac were dry rotted.. Now the one for Hvac it sticking out maybe a 1/4 to 1/2 from the firewall.. i can break it off piece by piece.

So basically all ill need to do to get my Hvac and vents working properly is by replacing the vac line from control to a T connector and one goes to ball other goes to intake and it should work.. Hmm i wonder how hard it is to dig out the Hvac line from inside.. If its too hard then ill just toss the ball. Prob give it away to someone on here.

thats for the vent control with out the ball the vents will be changing if useing the heat from floor to dash when accelerating the motor creates no vacuum under accelerating constan rpm it will have vacuum understand

Mr.E

good info i usually consider most vacume stuff as spare parts now i know why i never am comfortable. not doing this

98jeepsrt6

So theres two choices, either leave it the way it is with no HVAC controls, or run new vacuum line from inside vehicle to a T connector, which one vac line goes to ball and the other vac line from T goes back to the capped port on intake manifold.

I know my words seem confusing but its simple and frankly the vac system isnt to difficult to understand.. theres only three components that rely on vacuum. Evap purge solenoid, Cruise Control, and HVAC system. Vacuum Ball is there to hold vacuum.

dont think the ball does any thing with the pollution vacuum just the vent in dash and cruise which you deletedthin the hvac get vacuum direct ?

98jeepsrt6

well im going to get under my glove box and dash panel to see where that vac line goes and see how difficult it will be to replace the broke pne coming out the fire wall.

have fun you gotta tear it apart to get to it mine broke i got to it thru thr radio hole and spliced it

98jeepsrt6

Thats wat i really dont want to do, but i already have the radio out and when i look up inside from driver floor board i can see the lever and such for the hvac controls. Actually does that vac line connect to the controls under the radio or only to the doors when selecting where i want the air to go??

the controlis mounted on the side of the box where the ac evap and heater core are no mines an 89 i neve did see the thing but i pulled on the lines and found the color i need and and spliced it i might of even pulled out the ac control panel i cant remember all the exact thing but deff got to the line thru there
