Default Rear washer clogged

I just replaced both washer pumps and my rear washer still does not spray. Pump has power and functions properly. Makes me think the line may be clogged. Anyone have any "most common" clog site suggestions?

Pumping and making pressure two different things. Somewhere disconnect the hose and see if there any difference. As close to pump as possible .

Is stuff apart? Can you blow into the line? Thinking you can tell if it is clogged. Reason I ask is because my first thought would be that the line has a leak. Or maybe they use some connectors along the route and it is not one long piece of hose and something separated. No idea how any of that is routed but the hatch would probably a good place to start. Pretty sure I did see some connectors for the washer line in there when I fixed my latch and also when I replaced the bezel around the rear wiper where the little nipple had broke off.

My rear line was clogged on my 96. I disconnected it from the pump under the hood and from the wiper. I used my air compressor to gently blow out the line from the wiper mount and it cleared the blockage.

The check valve might be seized, it's underneath the hatch trim panel near the rear wiper motor assembly.
