HWH slideout intermittent failure
2006 Itasca Suncruiser 38T with HWH slideouts. On occasion the rear (passenger side) slideout will not respond to the switch, can occur for both extension and retraction. It will eventually respond after I have toggled the switch several times, deployed/retracted the slide lock, or operated the front slide, but not sure if any of these were the solution. Any ideas? Thanks!

Have you checked for a loose connection anywhere in the electrical circuit, or a poor or loose ground?
I've read that over 90% of all 12V problems are the result of a poor or missing ground, from personal experience I believe that is true.

I have a similar problem on occasion. Sometimes if I command the jacks down at the same time as the slide out, it will get a response and then work properly for a while. Loose ground is what I think also.

Trying to put the slide out the same time you are putting the jacks down is a sure way to damage the shuttle valve in your HWH system. Dont ask how I know. Perhaps, you shuttle valve is sticking, and what you are doing unsticks it.

The Hwh pump likes 12.5 volts.
Running the engine increases voltage.
Energizing the start boost switch will a!so raise voltage if all the batteries are good.

I agree with Ray (post 2), I'd sure look for a loose or corroded connection.

the switches that winnebago used during this time were junk. its not a hwh switch.
i carry a couple of them with me all the time. of course i use my coach a lot, so i understand some of it.
check the back of the switch. one side of the tabs run the pump motor, the other side
run the solenoids. both have to function for the room to move either way.

I have also experienced the switch not always making good contact when pressed. Also sometimes one of the relays for the pump motor may not be making a good connection. You may begin to determine what's going on by monitoring things out at the pump while another person operates the switch inside.

Any hints on how to remove the switch without breaking it? I think that's where I'll start my investigation.

Scooter21,
The ground on my Hwh pump electric motor was a worm drive hose type clamp around PAINTED motor. I established a better ground with a #10 wire to a grounding lug.
