Hi there. The link provided by Mr. Noname is a good description, except my cable was still fine, so I didn't do any drilling. In order to get the linkage out, you will need to disconnect the wiper motor, remove the AC belt, and remove the four AC compressor mounting bolts. Once the bolts are out, swing the compressor gently out of the way. I didn't care as much, since the AC on my car failed as expected. Next, if the driver's side pulley/spindle assembly has bound and resists motion, tap the spindle free from the assembly by:
1. release the cable tension (assumed already done) and drench the spindle's surfaces with penetrating oil.
2. twist on one of the wiper arm mounting bolts onto the threaded part of the spindle. This will allow you to de-gunk the threads if you miss with the hammer, something I didn't do. Tap on the spindle to drive it out the pulley side. There is a washer/shim between the assembly and the spindle. Save it. I did not need to completely remove the spindle, just tap it out an inch or so to get access to the inner surface of the pulley. Note that the pulley is a separate piece from the spindle: try to avoid separating them, but if you do, no harm lost. After this, clean and lube the spindle's shaft, the inner surface of the pulley that contacts the washer, and the back end of the assembly if necessary.
Clean and grease everything.
Reassembling the cable on the pulley and arm is tricky: I did it without an assistant, but one will be very useful. I started by putting the wedgy/square(?) end of the cable in its slot in the arm. If the cable end pulls through the arm, this is how the cable detatched in the first place, and it will need to be fixed before reassembly. Thread the cable over the pulley in its correct orientation, (the cable does one and a quarter turns on the pulley) and have the friend hold the cable in the grooves on the pulley while you stick the threaded end of the cable through the end of the arm and start the nut. Try to keep the pulley's position relative to the arm constant, or the cable will jump. Tighten the nut on the cable end quite a bit, and try a test run. Don't force the pulley to rotate farther than it normally does, or the cable will jump. This may happen to you ten times like it did to me- just reassemble and retension the cable, a little tighter this time. I tightened that little nut as much as I dared without stripping it, in order to not have to do this again.
Once the cable is tensioned and the linkage moves back and forth freely without jumping the cable off, you can put it back in the car, I think with the driver's side spindle going in first. Bolt it back on to the firewall, reattatch the motor link, park the wipers in the right spot, reconnect the wiring harness to the wiper motor, and save your new spare AC belt for when you get the thing recharged. I removed the idler pulley, too, since it rattled without the belt running along it.
Of course, if your AC still works (and it shouldn't by now), put the belt back on and cycle the AC once a month.
Good luck: I'll monitor the board if you have any difficulties with your repair.
