hydraulic slideout failure

[carsonevy]

Hi, I own a 2004 Gulfstream crescendo. The two front slideouts (living room and kitchen) will not extract.. I have checked the fuses and unable to solve the problem. Can someone please clue me into what could be the problem ?

I'm not familiar with your particular leveling/slide system. We have the HWH system that has a common electro-hydraulic pump that operates both the jacks and the slides. If your system is similar, does the pump run and the jacks still extend? That would eliminate the pump/wiring/fuses as the problem for the slides. Our pump failed once (bad motor ground) and nothing worked until it was replaced.

If the pump and jacks operate, but the slides don't, then I'd look at the solenoid(s) that control the hydraulic fluid to the slide cylinders. Are you pumping hydraulic fluid on the ground under the coach?

Just thought of another thing to check. Does your transmission have to be in Neutral with the parking brake set before the slides can be activated? If there's an interlock, you might be prevented from opening the slides.

Hope this helps.

Make sure the front seats are moved all the way forward.

Carsonevy,
You don't mention if you just purchased the RV. Or, if they worked prior and just quit working. So, I would add that in my Gulfstream, the driver's seat must be moved forward before the slide will operate. The seat has a slideout lockout switch.

Good luck.

Hi, thanks for your reply. The jacks still extract and upon inspection on the hydraulic pump we found that there seems to be a leak somewhere for there was oil on the drip pan. Thanks to all who have responded. The next step is to take in to the shop. We are getting cabin fever and are looking forward to full timing again. Hope to see some of you at one of the campsites along the way.
