Washer fluid issue - stumped

[Ericgcruiser]

Hi all, I swear that I searched and searched on this site, and I could not find the solution to my problem.

1. '91 Landcruiser (duel pump system - NO DIVERTER VALVE)
2. no spray out of front or rear nozzles
3. swapped out front pump
4. both pumps make noise when activated with switch
5. not clogged (tested with 6 inch hose from outlet of pumps. Solid gravity flow, nothing when elevated and pump is running)
6. Oh yeah, and reservoir is full

I am completely out of ideas at this point.

Nozzles are probably plugged up. Disconnect hose at nozzle and check for flow.

Have you tried switching polarity of the wires?

I considered that, as I did have to splice the wires to install new pump, but wouldn't I notice air being pumped in to the reservoir if this was the case?
