How hard was it to replace the wiper motor?

 

WELL...it goes sorta like this
1. with hood (bonnet for you Brits ) closed, remove plastic caps on wiper arm nuts and
remove nuts holding the wiper arms on.
2. gently pry up the wiper arms off their mounts.
3. remove the large nut & washers around each wiper spindle.
4. open hood, disconnect tubes from washer jets
5. remove plastic cowl piece...one bolt in the middle, 2 plastic push darts..one on each
end. it comes out sorta hard.
6. remove nut holding the wiper motor ground wire to the body ( unless your's was
broken off like mine was )
7. now you will remove the 6 screws holding the wiper motor / wiper linkages assy to
the body..unhook the wire harness..and lift out the assy and place it where
you can operate on it.
8. THIS STEP IS NOT IN THE RAVE..but you may thank me for this later....quickly , so as
not to alert anyone that you may NOT know what you're doing...whip out the camera
and snap a pic of the wiper arm "Transmission" paying special attention to the
POSITION of the link on the wiper motor spindle. I'll explain later.
9. remove the nut holding the link to the motor spindle, and the 3 bolts holding motor
to assy.
10. you may have to unhook one of the linkage arms by removing the clip that holds it.
to get at the nut on the motor spindle.
11. install your replacement motor and then reassemble all.......
barring any difficulties...this takes about 1 to 1.5 hours
TOOLS : 10mm end wrench, 13mm end wrench, large phillips screwdriver, pliers

And now back to step 8.......if you get the link that goes from the wiper motor to the wiper linkages back on and it's in the wrong place...which you CAN do cuz the link can go back on the motor in ANY position....the wipers will not operate properly....SO.. take a pic or drawing AND ...... after you reinstall the complete wiper assy, mount one of the blades and test the operation BEFORE you put all the cowling back on....cuz if it's wrong you will have to take the assy back out to re position the link. ( or so I"m told , LOL)

 

Thank you for sharing.

 

So, is this water related in any way? I noticed a posts about rainy/misty days making the wipers worse for one person.

I had my 04 DII detailed yesterday by a profressional shop as it is new to us and needed a lot of attention. I was thinking when I took it in that I should tell them to skip the engine as reading this site can make you quite paranoid of issues coming up! Of course I forgot to say anything to them.

The good news: the engine looks fantastic, years younger than it did before.

The bad news: I pressed the wiper arm down to dry brush some dust off the windshield and the wipers moved a few inches and stopped. I kept trying and they act very erratic. After about 5 minutes of playing with it they began to work normally again when I push the arm down (they run a full cycle and stop at the bottom where they should). But, when I twist to turn them on I hear a click in the dash, but nothing happens on either low or high. Could this be a water issue from the engine cleaning?

On the way to work this morning my wife called and said the service engine light came on. I have the ultragauge at home and will check the code later - I had the P0455 code last week - could be that returning I guess....

 

Catman, I doubt that the detailing is the cause of the wiper glitch.
Try this test: connect your volt meter from the casing of the wiper motor to the ground and run the wiper. If you see voltage great than 2 volts, the grounding point of the motor is toast
Easier yet is to run a #14 wire from the motor casing to the ground and see if the "glitch" is resolved. Of course if the glitch is resolved just leave the new wire in place and don't look back.
Most of the troubles of clean engines arise from preassure washing the engine bay. I like a clean engine so I use gentle preassure.

Thanks Dad! I am going to try that over the weekend and see how it goes!

 

A lot of wiper systems have a "parking" switch built into the motor and gear assembly
