Would X7 C5 wiper motors function if fitted on wrong side?

Unread post by Shea89 »

This is a silly question because I've done a silly thing. I did a 2 hour round trip to buy a set of wiper motors for my X7 C5, the guy let me test them on the car, they didn't work so I left them. Now I'm realising I had the motors on the wrong side, now the guy is a 3hr return trip away.

So before I waste anymore time, I'm wondering even though the motors were on the wrong side would there be any sign of life out of them in that configuration if they were in working order? (I'm pretty confident the motors themselves work but it might be a wiring issue with my car and not the motors themselves)

It's because one of the motors contains the master ECU (Right) and the other contains the slave ECU. So these have to be connected correctly as they are multiplexed wipers, otherwise they will not communicate over the network.
