kook911 Posted July 28, 2017 Share Posted July 28, 2017 I am having a problem with the pressure that come out of the nozzles. What I have done already is take all the lines off and blew air through each of them individually. All have air coming out them. Took the nozzles off and hit them with air/clean them and got air flow through them. I took the reservoir off and cleaned it out. I put everything back together and I still get low pressure out of them. Driver side gets some fluid out but it hits the low part of the windshield, but passenger side will not even hit the windshield. Could my motors be going out? Any help with this.

Pete M Posted July 28, 2017 Share Posted July 28, 2017 cleaned the wire connector at the pump? Link to comment Share on other sites More sharing options...
HOrnbrod Posted July 28, 2017 Share Posted July 28, 2017 ^^ This. If no joy, pull the pump out of the reservoir and clean the pump's inlet filter. If still no joy, it's pump replacement time.

kook911 Posted July 28, 2017 Author Share Posted July 28, 2017 cleaned the wire connector at the pump? I have not. I will get out the electronic cleaner and the wire brush and see if that helps. Link to comment Share on other sites More sharing options...
Green Mesa XJ Posted July 28, 2017 Share Posted July 28, 2017 It can also clog at the nozzle. I've had to replace them because they wouldn't clear no matter what I did although more often its slime in the water tank. No idea how bacteria grows in that stuff.

cruiser54 Posted July 28, 2017 Share Posted July 28, 2017 After those things, add a cup of white vinegar to the rezzy. Link to comment Share on other sites More sharing options...
kook911 Posted July 29, 2017 Author Share Posted July 29, 2017 OK cleaned up the wires and scrubbed the prongs on the motors. The pressure is still the same. ^^ This. If no joy, pull the pump out of the reservoir and clean the pump's inlet filter. If still no joy, it's pump replacement time. P/n 55154613 http://www.ebay.com/itm/WASHER-PUMP-MOPAR-55154613-/192247999012?epid=83228032&hash=item2cc2dfaa24:g:If0AAOSwkttZaM~7&vxp=mtr Can anyone let me know how to take the motors off, I tried but was worrying about breaking them. After those things, add a cup of white vinegar to the rezzy. I will do that tomorrow. Link to comment Share on other sites More sharing options...
Keyav8r Posted July 29, 2017 Share Posted July 29, 2017 One thing to think about is replacing/moving the reservoir. In preparation for installation of a double diaphragm brake booster, I picked up an XJ reservoir that mounts on the passenger firewall. It has two pumps, one for the windshield and one for the XJ rear hatch. I think it was from a 96. Buy a little hose and wire to reroute everything, bring the hose from the pump you don't use far enough up,that you can connect it to the hose to the sprayers and you have an installed spare pump. Or, you could go Hornbrod's route and fit the reservoir in the fender. I believe it was also an XJ reservoir with dual pumps, but I could be wrong.

I have two reservoir and they both have the duel motors on them. I just ran a hose and tee them together. Link to comment Share on other sites More sharing options...

Late 1991 up to 96 XJs have the reservoir on the pass side. I swapped one in to my 91 XJ, also in preparation for a dual diaphragm booster swap that is yet to happen (parts on the shelf, gathering dust). I did the late XJ inside-the fender-mount on my 91 MJ. I recommend the later one, although it is slightly more work. Much cleaner setup. I've experienced similar lackluster sprayer performance on my CJ. I've wondered if adding a relay to bring full voltage to the pump, similar to upgrading XJ/MJ headlight wiring, would make a difference. Link to comment Share on other sites More sharing options...
Rockfrog Posted July 30, 2017 Share Posted July 30, 2017 If you use an XJ reservoir with two pumps, use a check valve when you tee them together (or just wire them both up). If you tee them but only have one pump wired it will back flush back into the reservoir without a check valve. I just ran into this issue when I added the 97+ fender reservoir to my MJ. It'll barely hit the windshield when this happens. Sent from my SM-G930W8 using Tapatalk Link to comment Share on other sites More sharing options...
HOrnbrod Posted July 30, 2017 Share Posted July 30, 2017 I did the 97 XJ fender tank mod a few years ago. Ran the wiring and hoses from both pumps to a convenient spot in the engine bay. The pump motor wires were on connectors, and the unused hose was capped off. So when the windshield pump craps out, you simply swap the power connectors and hoses and you're back in business w/o tearing into the fender well. You have a spare pump - might as well use it as a standby. Of course, this only works once. I already had one die so next time it's back inside the fender to replace both pumps... :rotfl2: Link to comment Share on other sites More sharing options...
Rockfrog Posted July 30, 2017 Share Posted July 30, 2017 Meh, both pumps can be reached without removing the fender ... and they just press into the bushing. I couldn't wire both mine in as the upper motor used a different style connector (same deal on my 2000 XJ, not sure why they did that). I've only had the lower pump die on my XJ, since new. But at least they aren't held in like the older pumps (the strainer screws onto the pump - inside the tank).

Rockfrog Posted July 30, 2017 Share Posted July 30, 2017 Just the rear section, the front (from the apex forward) is trimmed away. Yeah, forgot about those doodads, easy enough to pull aside, I did have them on my XJ when my pump died though.

schardein Posted July 31, 2017 Share Posted July 31, 2017 I think they use different connectors so you don't get them mixed up on the XJ. Try to clean the windshield and spray the back glass instead. Link to comment Share on other sites More sharing options...

Yes. That's the way it is in the dual pump XJ tanks - the power and and output hoses are completely segregated. Link to comment Share on other sites More sharing options...
