For the past six weeks or so, B0XY had been victim to the "rocks in a blender" noise coming from the windshield wiper motor. I found a write-up somewhere that included step-by-step instructions on removal and repair. However, that write-up was a little vague in a couple of spots. I didn't take photos, but here's some more info on the process.<p>1) Remove 3 10mm bolts holding the wiper motor to the firewall, and unplug the motor.<p>2) Remove spring clip from silver wiper arm (top of passenger side footwell), and remove 10mm bolt on gold-colored arm that connects the output of the wiper motor to the wiper arm. I had to wiggle this one off, it was on there pretty solidly.<p>3) Yank wiper motor off the firewall. Mine was held on by a thick silicone/elephant snot sealant, and was a bit of a pain to remove.<p>4) Mark the orientation of the motor "cylinder" at the cap and the base. There's a little spike to help you line up the bottom, but mine wasn't very distinguishable. This will also line you up when you put the long screws back in.<p>5) Unscrew and remove the two long flat-blade screws holding the cap on the motor "cylinder."<p>5) Remove cylinder. Everything's magnetized in there, so it may not be that easy. I couldn't get the cap off, I had to just pull the whole cylinder off.<p>6) If the motor "core" (armature?) stayed in the base, LEAVE IT THERE! It's a pain to get back in. If it followed the rest of the cylinder, it means a little extra work.<p>7) See which of your magnets is unglued - it will be obvious once you get the core out.<p>8) Clean the cylinder and magnets up, and get your Krazy Glue out - the Gel kind makes less of a mess. Test-fit the magnet so you'll know where to line it up, then glue and clamp. Let sit for a while, until you're positive the glue has set.<p>9) If your "core" came out, now's the time to put it back in the rest of the assembly. There are three spring-loaded magnets that surround the end of the motor core by the wormscrew end. These will be a pain to work with.<p>I ended up using a combination of zip-ties, needles and electrical tape to hold them in a compressed position to get the core back in. Resist the temptation to pop off the metal tabs holding the springs from the back - if there's any rust at all, they WILL break.<p>10) Once you have the core seated properly, remove whatever devices you had to use to get the magnets out of the way, and finish reassembly.<p>11) Bolt the motor back on with the three 10mm bolts, and reattach the gold-colored arm to the wiper motor - one direction will put it closer to the silver wiper arm, so pay attention there.<p>12) You may have to move the wipers themselves to get the silver arm back in position to clip on to the gold-colored arm.<p>13) Snug up all the hardware, and plug the motor back in. It will probably scare you half to death as it fires up to realign the wipers.<p>14) Test your now-quiet wipers.

Yep, that's the walkthrough I used. Very helpful, but I wanted to document the surprises I came across.

Re: Notes on wiper repair (Splat)

Very helpful. <p>What about the wires that plug into the motor? Mine are about to crumble and we were thinking of replacing them somehow. Or should we leave them alone?

Dagmar;<p>I thought you were about to acquire a '91 240 SE!<p>Your '87 is the last year 240 with the really bad wiring that deteriorates over time from fumes and heat (and engine cleaner!).<p>Once you start cutting into the wiring harnesses it become nearly impossible to find a good tie-in place.<p>Replacement harnesses are out there and VERY $$$.<p>George Dill<p>

Or can we tie them into the wires that are coming out of the firewall? They are still color coordinated...but just barely <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/eek.gif" BORDER="0"> <p>My gut feeling is to leave it alone unless the whole harness comes out and that won't happen on my watch.

The new owner of the '87 wagon will need wipers when on vacation at Callaway Gardens.<p>George Dill

Mine haven't worked in 3 years and I haven't missed them much. Rain flies right off if you're going fast enough. Fog and dew is bad though.
