W 124 Wiper Repair

I have a eurpoean import 1986-87 300D wiper that was starting to get slow and beginning to shutter when moving. It seems to not have the same speed between normal and fast when switched to that mode. I got a used 1991 replacement (entire assembly) and installed it just fine. But when turning it on it does not stop or obey the switch signals. I have to turn off the key. I noted that the motor number is slightly different but other than that everything seems identical. I thought the 124 series wipers were interchangable if it would install correctly and everything else. Does anyone have any experience with this? Have I installed the wiper properly?

Check to make sure the pin assignments are the same on the harness that connects the wiper motor to the stalk. Personally, I would've just taken apart the whole wiper assembly (early ones used the much beefier solid alloy lids on the mechanism necessitating the disassembly of the linkage) and lubed everything with Gleitpaste and strategically placed drops of ATF).

Did that to mine and it works like new now (going on 2 yrs).
