The windshield washers on my E39 530i have quit working completely. Reservoirs are both full. Wipers (and therefore the switch, I assume) are working normally. Fuses look good. Does anyone know what might be causing this? Is there a relay for the washer pumps that may have failed? And, if so, where is it? Thanks in advance for any advice. I've ordered a Bentley manual now that I'm past my CPO warranty, but it won't be here for a few days and we've already had some winter weather here in Colorado so I'd like to sort this out as soon as possible.
