Help with wiper motor & switch

If it's a non-A/C car, I find it easier to pull the whole wiper transmission out as a unit to work on. Still not easy, but, less frustrating than standing on your head trying to repair it under the dash. If it's just the drive link, you can sometimes work on that once you pull the wiper motor from the cowl and just leave the linkage and pivots in place. That will depend on the condition of the rest of the system.
