'05 Bus Rear jack not working

Today the driver side rear jack did not come down; remained in the up position.
Where exactly is the HWH reservoir located for me to check fluid level on this Bus?

It is the '05 38 TGP model.

Since it has been working all along and tonight we are in a site requiring front jacks to be fully extended I am hoping for a simple fix like low fluid level.

If so, we are close to a WM super center. What type of fluid can I use?

Thanks in advance.

My reservoir is attached to the pump, can be tracked by the pump noise.
In 99 the system used ATF III, but I think HWH now has there own fluid.
All levelers to be retracted before adding fluid.

Automatic transmission fluid compatible with Texron III transmission fluid can be used in HWH hydraulic jacks. The original HWH fluid does not have the red dye that transmission fluid has. Whatever you do, do not use hydraulic jack oil.

Once you find the pump and reservoir, check the fuses on the control board. If one is burned out, replace it. If it blows again right away, I suspect you may have a burned out solenoid.

Finding the HWH reservoir is proving to be difficult. I have crawled under front of coach and searched the engine area.

'05 owners, can you help on where the HWH jack reservoir is located?
Thanks

on my bus the pump and circuitry. I believe the reservoir also is behind the pump. those are located next to the battery compartment if I remember correctly. I have a 38dp but I cannot imagine them not having it in the same place. It is on the drivers side. I believe it is the 5th door from the front. If you look for the circuit board in there all of the hydraulics are behind it. The bay I am talking about does not have a floor and is open to the ground.
