Windshield washers not working

If I check the voltage on the cable connector with a very good multimeter, it reads 9.6V even when the car is off, no key in ignition. On turning on, and clicking the wheel wand for spray, no change in voltage, still about 9.6V.

I read somewhere that the wiper relay could be bad in the E-box.
1. Does the wiper relay also control spray motor?
2. Can i test the relay before purchasing replacement? Can i swap in another relay from the e-box?
3. If I have to replace the pump, will any aftermarket pump be ok?

Did you ever figure out what the problem was? I'm having the same issue.

I recently bought a 2005 330i. Mine came with headlight washers and they ARE working but the windshield washers are NOT working. I checked to voltage on the windshield washer connection and it reads 9.3V even when the car is off and the key is out of the ignition. The headlight washers read 0V when the car is off and the key is out of the ignition.
I checked the fuses, they are all fine.
