Hello Folks! New member here with a 2003 Patriot. New issue, the big slide doesn't extend and the leveling system faults out. The tank was low on oil so I serviced it with 2 qts and filled it. I can hear the power really clicking in the back but the pump doesn't come on. Any direction from the gurus here would be appreciated.
Edit: the tank I serviced is in the rear right corner when raising the servicing door there.

If the pump won't run there are a few possibilities related to power to the pump motor.
1) check for power at the motor solenoid supply.
2)!check for a proper ground to the motor pump
3) Try using a jumper cable to jump across the pump motor solenoid ( it's possible you just have a bad solenoid).
If you have a good source of power and ground to the pump motor and it still won't run you may have a bad motor or a seized pump .
If it is just the motor not working with power applied try tapping on the motor with a hammer ( not hard ) to see if the motor brushes are just sticking or not making contact .
Did you top up the reservoir with the leveling jacks up or down and slides in or out ( every thing should be retracted before a top up)
Hope this helps

I don't think you filled the hydraulic reservoir for the slides and leveling system. The pump (#22 in the diagram) is likely a gold cylinder on top, a thick square plate with 4 hoses connected then a black cylinder at the bottom which is the correct reservoir. There is a cap on the tank you can remove and fill with oil. I think it's 1.5" from the top of the fill port, but that is just my memory. There should be a sticker or a fill mark. You can get a 18" rod to stick into the reservoir to see the level like a dip stick.
