This is a dead Lucas wiper motor, as used in 1970 and later Saab 95 and 96 cars. It ran very slowly on one speed only, and refused to self park. After close to 40 years of work, it needed some attention.
This motor was actually less grubby than most of the motors I get to rehabilitate.
Now the ancient motor is CLEAN [!] and has a new brush and spring plate installed, and the self-park mechanism has been repaired. Speaking of ancient parts, I built that Heathkit multimeter in 1956. It still works like new!
Here are all the "guts" of the Lucas motor, just before reassembly. The self-park switch is out of sight, mounted on the main motor body.
The moment of truth. The motor is mounted on the test board. Yup, it works on both speeds [at the correct rpm for each speed] and it self parks. Voila!
Looking better than new, Lord Lucas' wiper motor is ready for another 40 years of work...
When you send us your wiper motor, you can expect a quick turnaround time and reliable wipers for years of rainy days to come.
