Wiper Motors and bench testing them.
Every so often we have illogical returns or complaints about certain brand new or U.S. reliably rebuilt parts not working. One such part is the GM series of wiper motors based around 1968-84 various models that are returned..., not parking, not starting, DOA.. brand new parts.. they're checked & pretested at the US assembly point.. often genuine re-manufactured etc..
A thought to keep in mind if you get one..... regardless of were, who or how you get one ... new (if made) or reco or ex a mates junker etc etc....... don't just "bench test" a wiper motor it by sticking a wire here or there. .... don't try to figure out the "irrelevant fact" that some come with 3 wire terminals & another 2 .... or 4.. by touching a wire here or there & hoping somehow.... it will pop out magically with multiple speeds & auto shut offs working etc etc.
Often by there you have stuffed it... ! simple as that.
Similar example... we had a very unhappy fella with a brand new window motor at our door at 9am.. pissed off & claiming similar.. claimed DOA expletive etc etc.... but he had put a + & - on the 2 Up / Down terminals at the same time....... Luckily it did not fry it. Simply he did not know they need a body earth and single power up or down only & we powered it up correctly in front of him.. and he left. Lucky it was not a wiper motor.. or theres a 90% chance it woud have been stuffed.
Just like household electricals.. they're so unforgiving.. be careful out there.
Maybe buy a good digital multi-meter and watch a few videos on how to skill up and use it well.
..... make sure your wiring is right.. your cars earths are strong..before you buy one. Could it be a burn't out wiper switch?? maybe its one with AUTO PARK ? .. ...and make sure IT works too.. don't stuff up pulse boards etc..
Get hold of a wiring schematic or look up youtube for wiring demo / testing wiper motors vid before you do buy one maybe..? and google "Wiper Diagram" IF you need to test a new one.. if you do .. ask why...first.. before "testing it"...
Attached below is a link video test proceedure if this helps anybody out there., it also goes over some of the 6 or 7 wiper switches that ALONE are fitted to various 70-81 Camaro's.
It's far too easy to wreck good electrical parts & pass the blame.. and certainly after being cross wired, especially on a converted dash or home made fibreglass mount etc.... they will NOT WORK.

   

You tube video  https://www.youtube.com/watch?v=nFtDOmpRzRA But be careful.. do NOT earth any of the 3 splade center pins..you will blow the motor. It is earthed via the side strap.. watch the video.
