HWH jacks fail to store.

[Tom and Patty]

Before I tear into the dash area, maybe someone can help us out.
Intermittently our jacks will fail to store. I do hear a solenoid "click". Frustrated one day, I flipped the HWH panel closed , opened it back up, pressed the stores button, and the jacks stored.

I'm guessing that it is a connection, but I can't see where the wires run without moving ducting ect.

Ideas ? Thanks

Hello Tom & Patty:

The connection plug under the dash to the HWH panel could be loose. Just to let you know that there is a shuttle valve in the manifold of the HWH pump & Solenoids. If the valve is sticking it could prevent the jacks from retracting. If you were to loosen the valve with a ¾"� wrench it than allow the jacks to retract. That may be your problem.

Have pulling the Dash apart.

When we picked up our coach @ the factory, the drawer w/the HWH controls was somehow inhibited by the wiring behind it, pulling on the radio & clicking an HWH solenoid when opening & closing the drawer. You may have a minor version of that problem that has accumulated over the miles.

T&P - On mine there is a cable that runs into the back of the control panel in the control drawer. The cable runs to the control unit where three or four connectors go between the hydraulic units and control panel. I have seen problems where one of the connectors are partially (sometimes completely) pulled loose and cause intermittent problems similar to what you described. Sometimes there is strain put on the cables when the drawer is pulled in and out. You might try reseating all the cables once you get the courage to tear the dash underpanels off. The panels are easily removed.

Might try taking out HWH membrane push button operator pad (4 screws to remove), lift the operator pad out (gently) and check the 5/C wiring harness connector supplying the opr pad. The connector on mine came off once and I could not store jacks. Reconnected pad and went on my way. Later, rerouted wiring harness to relieve stain on connector when pulling out the drawer.

Thank you everyone. We are going camping this weekend and I'll be playing with the ideas Saturday I've already pulled the four screws and checked the multi-pin connection. It is the wiring loom that disappears into the floor of the dash that has me wondering
