Rear window wiper extendor

If after all this time you still need to replace the back wiper.
There is a plastic lever where the wiper attaches to the arm.
Squeeze this lever against the metal wiper arm, while pushing
the wiper blade towards the base of arm. It should unhook
the blade from the wiper arm.
Good luck.

The wiper arm has a cover on the left end that pops up after gently spreading the two bottom sides apart. That allows the arm to swing out for cleaning the window or replacing the blade.
The wiper blade assembly attaches to the end of the arm . It is pressed in and will pop out with a little force rotating the left side away from the arm. It pops back in with a little push. The arm remains attached to the rotating shaft assembly.
I believe you can then replace just the rubber blade and not the whole blade assembly, if that is your fancy.

1. Release the old blade. Lift the wiper arm off the window.
2. Remove the wiper. Once rotated, the wiper will release from the wiper arm with a gentle click.
3. Position the new blade. Place the small bar attachment on the new wiper blade into the hook on the wiper arm.
4. Lock the blade into place. ...
5. Done!

How to change the rear wiper on a 2003 Pontiac Vibe

The 1998 Dodge Grand Caravan has the most common hook-end wiper arms. See related links below for installation videos. Also, purchase the replacement blades first and there will be additional instructions/illustrations on the replacement packages. Locate and press the tab or button where the wiper blade is inserted into the hook of the wiper arm and pull wiper blade out of hook. You may have to rotate and flex the blade to make enough clearance for the hook to pass through.

1998 Dodge Grand Caravan Wiper Blade Size Options w/Correct Lengths & Attachments

the rear wiper arm is attached with a single nut in the center,
1.) pry the cap off that is covering the nut. It pivots toward the
blade.
2.) Remove the nut holding the blade assembly.

3.) lift the arm back and forth to get it off the shaft

Good chances are that the motor has gone bad and will need to be replaced. It's a common thing for the rear wipers to stop working,

You can try this first if you got time:
Take the rear hatch apart (screws, spring clips, inner panel screws (12), etc) to get to the wiper motor. Close investigation, the gear box attached to the motor can be opened up. The motor obviously works since it chatters so something else is not working, makes sense. Opened up the gear box, the motor shaft drives a worm drive gear (plastic) that meshes with a gear wheel (plastic) that has an eccentric cam (metal) on the gear wheel that attaches to a metal arm that meshes with another metal gear arm that is attached to a long shaft that passes through the hatch door and terminates with the finely spline end of the shaft (where the wiper attaches to). As the eccentric cam turns around the gear wheel, the metal arm moves back and forth thus creating the wiper effect. Lot of action in a small space,(pretty cool actually). My basic philosophy is that if something can be assembled, it should be able to be DIS-ASSEMBLED (in theory anyway). So fiddling with the thing eventually led me to the conclusion that if you put the wiper nut on the end of the wiper shaft and gently tapped the nut, you could drive the wiper shaft (and its metal gears and arms back out through the metal housing (Oh, forgot to say that the wiper shaft was "rusted" in its sleeve and would not oscillate back and forth). At the end of the shaft (on the outside of the vehicle) there is a metal "washer" that was an incredibly tight fit (this washer holds the shaft from falling into the gear box) so you have to keep tapping on the end of the shaft to eventually drive the shaft past this holding washer. Once you get past the washer the shaft would not pass through its guide sleeve in the metal housing (remember, "rusted" in place, seized). So tapped it out with a Phillips screwdriver acting as a long punch. You can then cleaned the interior sleeve by reaming it with a long circular steel brush (3/8" diameter brush that is designed to clean out push rod holes) and polished the wiper shaft with fine sandpaper, then lubed and reassembled the whole smash making sure the wiper shaft now moves freely in its sleeve. Put it all back together in the vehicle and we'll see if it works. Fingers crossed. This may save you some money if it works.

1. REMOVE RR WIPER BLADE

1. Raise the rear wiper blade to the position as shown in the illustration where the meshing of the claw disengages with a clicking sound. NOTE: Be careful not to break the claw.
2. Pull straight the rear wiper blade to vehicle's left from the wiper arm. NOTE: Do not fold the rear wiper arm with the rear wiper blade removed from it.

1. REMOVE REAR WIPER RUBBER

1. Place the rear wiper with the rear end of the rubber protruded from the blade stopper as shown in the illustration. NOTE: Do not pull out the wiper rubber forcibly, as the backing plates will become deformed or the blade claws will become damaged. HINT: The rubber can be easily pulled out by pushing the middle area of the blade.

1. INSTALL REAR WIPER RUBBER

1. Install the 2 wiper rubber backing plates to the rear wiper rubber. NOTE: Be careful to observe and keep direction of curvature for correct replacement.

b. Insert the rear wiper rubber from the claw of the middle of the rear wiper blade into the rear end position.

c. After passing the rear wiper rubber through the rear end side claw, protrude it from the rear end stopper and pass it through the front tip side claw.

I had a 94 wagon, and have a 99 wagon, and 2001 wagon. I think what you need there is a new rear wiper arm. This is about 44 bucks at getsaturnparts.net. The problem is getting the old wiper arm off without breaking the rear window. The corrosion between the wiper arm and the motor output shaft basically turns the metal into one piece, which may well explain why your arm spring is not holding the arm close to the window. Also explains why you cannot find used saturn rear wiper arms or rear motors on ebay. There is a small sliding lock at the base, but having moved it aside you will find the corrosion will not let the arm go anywhere.

Having done this twice, my approach as follows:

Get a new wiper arm

Take a hack saw and carefully saw the top of the wiper arm off exposing the motor shaft end. After spraying WD40 or other corrosion remover on get a small gear puller and pull the arm off the shaft. Use never seize and slide the new one on.

No...blade comes off end of arm... If in doubt, most "supermarket" style parts outlets will put it on for free.

The 2006 Toyota RAV4 takes a 24" drivers side, 17" passenger side and has a special 17" rear blade. Don't just go by lengths though - when buying windshield wiper blades be sure to always use the application guide book at the store or now-a-days you can Google 'lookup wiper size'.

You want to look this up because correct wiper fit is more than correct length, it's also proper attachement. Not all attachments fit all arms. Using the application guide or looking up wiper size online will avoid headaches of buying the right lengths with the wrong attachements.

The replacement wiper blades will come with step-by-step, illustrated instructions and once you have the instructions and the wiper blades/arms in your hands in front of you, it will all make better sense and will an easy maintenance task. Very simple and takes 5-15 minutes usually not requiring any tools. If in your budget, upgrade to the newer-style frameless "beam blades" which perform better than conventional framed wipers. I use Trico NeoForm Beam Blades which are fantastic. Hope this helps!

PS: Your question is about the front blades but if you address the rear blade too, this vehicle has what they call a "Roc Lock 2" rear arm. You can go to your dealer or I know Trico makes an "Exact Fit Rear Integral Blade 12-A". There may be others available too. I've got the Trico on my Jeep and it fits/works great.
