I installed a rear wiper on my Jeep, and everything works awesome. Except for the fact that I don’t have a rear wiper washer line. I was expecting to find one, but after looking at the tailgate, the pillars, floorboard, and engine bay, I can’t find it.

So, I want to create my own.

Now, I was told that I would need a dual washer pump, but in order to get that, I have to run some vacuum line from the engine to the tailgate.

So can anyone tell me where the line is supposed to go? I’m looking for where it enters the cabin, where it goes in the cabin, (does it follow the floorboard or along the passenger side headliner?), and where it enters the tailgate. I can’t find much on replacing the whole line, just repairing the tailgate part of it

Thinking a '95 is different then '97 and up but in my '00 there are 2 pumps.
Also it appears to come through to the hatch on the passenger side.
I noticed this when I scoffed a hatch from the boneyard.

a '95 has a dual pump washer bottle

If your vehicle originally lacked this feature, you may be battling

I can take a picture of where the hose emerges from the wiper mechanism

mine rear one has never worked

I have obtained a spare dual motor washer bottle, as my front one failed, both motors work in it

there is a youtube that shows how to change out the bottle

You will need to run hose all that way back to carry the water

From the 95 FMS
That's the best I can offer.

The hoses passes through the firewall directly behind the charcoal canister, about 2" inboard from where the lower HVAC Box Mounting Stud comes thru, both right above where the drain hose comes out. It then follows the taillight wiring along the passenger's side floor before going up the rear-most pillar on the passenger's side.

Okay. Thanks for all of those replies. If it follows the harness, then i’ll just run that line beside it to the rear.

Another question though. Right now, with the single motor washer pump, the “wash” side of the switch doesn’t activate the pump. Im figuring that it’s not supposed to, since it’s only a single motor washer pump, but at the same time I feel like it should activate it, but not the front wipers.

There are separate pumps for the front and rear, two separate connectors, etc...

The hose is already in the wire harness!
You need the dual pump tank for a 91-94. Those wires are also there.
As far as the switch goes, it mounts on the dash. AGAIN! You already have the wires, connector for that switch, and all you have to do is open up the hole with a knife to mount the switch.
A new switch can be had at Autozone.

Oh it is? I’ll check and see if I can find it. I have my doubts when it comes to some stuff on this Jeep, because someone decided that 16 gauge solid copper wire was good enough to be run everywhere in my Jeep.

Anyway, I already have the switch mounted and plugged in. Works like a charm too. But I originally thought that I needed just a dual washer pump, not 2 individual washer pumps and the tank to go with it.
