When you activate it does it make the “whirring” sound like the motor’s spinning? I recently did a thread because my ‘95 was barely shooting the fluid onto the windshield. I blew out the lines, replaced the nozzles and the wiper motor. Wiper blades cycled perfectly still.
End result: it’s WORSE! The blades on the replacement motor are noticeably smaller than the OE unit. I think that’s the culprit. After all the tinkering I was too pissed and disappointed to do anything more with it so I just left it as is and now carry glass cleaner and a microfiber towel.
