Help!!! Gulfstream Conquest slideout not working

Always glad to help.
You may want to download some of the Equalizer System manuals. To help with troubleshooting the slide and jacks.
You should find the heavy duty circuit breakers. Just in case one ever trips. They look like this one.

Giving model number would help with your problem. Is parking brake on. Some models require that engine be running.
In one of the basement compartments is a set of HD circuit breakers. The one for slide may have tripped.

Thanks..it is a Gulfstream Conquest model 6316. I've found a basement compartment with the slideout motor and hydraulic fluid, but don't see any kind of switch.

Thank you ronfisherman!!!!!!!! Parking brake did the trick!!!!!!!! Now I'm a happy camper!

On our 6316 those heavy duty circuit breakers are mounted up high on the back wall of the compartment that contains the batteries, the slide motor and the slide reservoir. They are difficult to see unless you get down low enough to look up high on the back wall. There are four of those breakers. If they are tripped or if you press the reset button you will see a 3/4 inch black plastic lever pointing straight down from the bottom of the breaker. The word RESET is on the lever if you look closely. Carefully rotate this lever back up in to bottom of the breaker until you can't see the lever any more. The breaker is now reset and should be ready to go.
