Wiper pump is leaking pretty bad, how do i fix this? 2000 explorer sport 2dr. I'm pretty sure i did the damage when i re attached the arm to the passenger side wiper which wasn't moving. That's all good now, but i've pulled something loose and when i spray, the fluid still makes it onto the windshield properly, but i'm also getting quite a bit coming down just behind/ to the side of the driver side wheel well. Thanks everyone.

Try this test. With the key OUT of the ignition stand outside the vehicle, reach out and try to move the broken wiper blade by hand. Does it move with no resistance? Does it feel like 'clicking' as you move it? Does the other wiperblade move slightly as you move it or does it not move at all?
This will help work out if it is the wiper arm slipping on it's drive spindle or if the problem is deeper down underneath in the rods and arms moving the wiperblades. Please comment below with this information and I'll try to help you more.

Their is a clip that holds it on the spline
Look AT THE CLIP .
Can you see how it works .
It s a clip

Wiper motor arm disengaged or slipping on drive shaft.

Wiper arms slipping on splines at pivot point of wiper arm.,,,more likely.

Wipers are held to drive splines with a 10mm nut.

Make sure wipers are in in 'parked' position buy turning on ignition and making sure wiper switch is OFF.

Turn off ignition.

Pry off the black round plastic cover off the arm where it attaches at the splines. ( Drive splines on lower windshield cowl.)

Tighten nut/s.

need a new head gasket. not a good sign
very expensive
stop driving before more damagee is done

bad bushings most like the radius arms

Very common problem, most likely needs a new wiper motor. Cheap fix.

The only way water can get into the cab is either a blocked air vent drain, leaking windscreen seal or rubber, damaged panel joint, badly sealing wiper arm. badly sealing door. Try and follow a possible trail. Water will move great distances before dropping so the leak could be far from the results.

The wipers are parking in the middle because the timing mechanism is off. Once they start doing this it seems to continue to happen so the 1st suggestion is to replace the wiper motor. If U don't want to spend the $ right now it's a pretty easy fix to reset the timing. Park the wipers & remove the wiper arms. Then remove the plastic cowling that covers the wiper motor & the motor assembly. Turn the wiper assembly over without turning the motor. Remove the nut on the arm of the motor. Repostion the arm pointing away from the closet wiper directly inline with the short arm. reassemble.

replace the arm and the wiper transmission.

the little pump inside the washer fluid reservoir is bad, replace it
