Vacuum Box open line?

Replacing the battery on a 1998 Mercury Mystique I noticed what looks like a vacuum line attached to a 8''x8'' box under the battery platform. The other end of this vacuum line is not connected to anything. Should it be?

The other end of this vacuum line is not connected to anything. Should it be? \r\nI connected this tube to a 1 inch vent tube on the side of the new RayOVac battery - the previous battery didn't have a vent tube.
    Should I have done this?

My 1998 chevy blazer is stuck in 4wd hi makes clicking noise under clove box

Clove box! How cool, you can bake a ham as you drive. (sorry, couldn't resist). Noise under dash is probably because you have a vacuum leak somewhere and a blend air door is flapping. Part of 4wd system is vacuum operated. There is a vacuum can under the battery (brilliant placement, huh) and the lines to it often fail over time. Use a vacuum gauge and piece of hose, one end in ear, to listen around for a small whistle = leak.

What is the open vacuum hose on the battery tie-down on a 1998 mercury mystique?

As batteries produce hydrogen while operating, this hose is more than likely provided to remove this highly inflammable gas from the battery compartment.

  • Bank 1 sensor 1 O2 Sensor. Also with this or they are very known for an intake gasket leak. Make sure to check your vacuum hoses first.
  • First check for vacuum leak from a hose. If none are found switch that top O2 Sensor (upstream) If this persists after all that you may have an intake vacuum leak.

I have shorted out the electrical system in a 1998 mercury mystique. I still have somethings like the horn, headlights and dashlights but not the power locks, windows, brake lights, signal lights etc. \it...

Check all of the fuses located in the black box under the hood close to the battery on top of the inner fender. All power to the car begins there. Check for large fuses 30 amp to 60 amp. Make sure the heater fan is left unplugged. When working on components under the dash always disconnect the ground cable from the battery

I have a 1998 Mercury Mistique. The heater fan is not working. It's located under dash but I want to know if I can get to it from the glove box.

Yes you can. Open the glove box then "lightly" pry the the sides of the glove bix inword. If you do 1 side at a time it makes it a little easyer. When you open the glove box, if you look between the box and the dash you should find a white plastic stoper on either side. You can "lightly" pry the box to move it past the stopers and it will flop open exposing the blower moter. note: empty the glove box before you do this. I know any idioty would know to do this right....... not this one. sometimes i amaze my self at how stupid i can be LOL o well..... hope that helps :)

Comfort controlode on 1998 corvette

Apply vacuum to the black/purple vacuum sorce line that is located under the glove box. if the Vent controls work properly then the problem is between the vacuum source and where the vacuum enters the cabin.

The Vacuum tank is located under the battery , but it has to be accessed by removing the RF wheel and the body panel behind the wheel, then you have to take out the computer. Battery acid wrecks havoc in this area, look for broken or disintigrated lines or bad vacuum switch or tank.
