Yeah pull the passenger side kick plate up and see if the wire trough below that is full of washer fluid. If it's not then start tracing the hose from the pump until you find where it's pinched or kinked. Heck you could disconnect the rear washer hose and see if washer fluid comes out when engaged.

The kick plate looks like this and just snaps on. I remove it back to front.

I will pull the kick plate and check it out. Can you clarify why the fluid or the line could be down there when all the other threads I’ve read say the line is up in the head liner?

The hose comes in through the firewall and then goes into the headliner. The hose can come apart just inside the firewall and the fluid runs down there. I don't remember seeing it, but I have heard there is a connector in the hose near the firewall.

Here’s the latest:
The pump and relay are working. I disconnected the rear line at the reservoir and attached a temporary hose. It pumps out fluid when the rear wiper is operated. Once again I tried to blow air through the line from both ends and it was unsuccessful. It’s blocked somewhere. I’ll get pics later but I’m 99% that the rear washer fluid line is running along that channel in the floor on the passenger side and not in the headliner. I can’t mentally process that the line somehow became pinched or blocked.

I think the rear washer fluid hose runs along the floor to the C pillar and then up into the headliner. I may be wrong it, may be that it goes up at the B pillar though.

Is the C pillar at the very rear where the seat belt is?
Yep. The A pillar is at the windshield. B pillar has the front seat seatbelt, C pillar has the 2nd row seat seat belt and D pillar is at the tail gate with the 3rd row seatbelts.

So no then to it being at the very back…. The very back is D.

Is there a likely area or areas where it might all of a sudden become pinched?

It should not move anywhere, except at the tailgate. However, the hose could be moved from working under the hood between the washer pump and the firewall. I suppose it could also get kicked or moved inside the firewall near the passenger kick panel. It bends and moves every time you open the tailgate, mine broke where it goes into the roof panel.

I really like the @Hamfisted posted of using a vacuum pump. Try pulling a bit of vacuum pressure on it and then hit the switch for the washer pump.

Mine had stopped recently for some reason. I didn't really care I pretty much never use it, but this thread got me to thinking about it again. I just hit the switch for like 15-20 seconds and washer fluid started flowing out the rear jet again.
