I had the same issue with my original Trico wiper motor. It didn’t work at all, then I soaked it with ATF tranny fluid and it did work better but it would stop with just a little hand pressure. I sent mine to Fricken Wiper Service (aka the Wiperman), as Cletus1950 has suggested. And as he said, parts are nonexistent. Rumor has it, when Trico went out business, they sold all of their spare part inventory to only a couple of people, with one being the “Wiperman” and they do not sell any parts.
Shipping from the Netherlands may be costly. You could always email or call to see. Another alternative would be to install an electric wiper motor. Most of the cheap wiper motors (made in China), the choke cable is in the way requiring you to move it. The only one that installs without any modifications is one built in the USA by Newport Engineering. It sells for 250 US dollars which is about $75 more that the Chinese imports but from the reviews on this forum, that is what I recommend.
Good Luck with whatever choice you make!
