I have a 2005 Cardinal with 3 slides that I bought new. For the past two years or so, the opposing kitchen and couch slide will sometimes stop short of full extension, or full closing. The bedroom slide always goes in and out first. If the bedroom slide moves slower than normal, I know the bigger slides are probably going to stop short of their mark. When the slides stop moving, the pump motor still runs and sounds normal to me.
I have tried many fixes, but the intermittent problem still occurs about one out of every 10 operations. I have replaced both batteries with group 29 marine batteries. I have tried jumping the batteries with the two in my truck. Replaced the slide pump/motor and fluid. Cleaned all electrical and ground contacts to bare metal. I have added additional grounding to battery from pump motor and Trombetta relay. Increased fuse size from 30 to 50 amp. Increased 7 amp slide switch to 15 amp switch. Dry lubed all mechanical friction points and gears. The hydraulic system never leaks fluid. I always level my rv before moving the slides in or out. I run the slides while hooked to my truck and shore power. My batteries show over 14 volts while charging and moving the slides.
One interesting clue is, I can wait about 10 minutes and/or momentarily reverse the slide switch. For some reason the slides will come to life with amazing power and immediately close or open as I originally desired.
I have talked to many folks and read many web pages. But I am flat running out of ideas. I would take the slide-out issue to a dealer but fear they would keep the rig 6 weeks and tell me it never messed up for them. The parts I have changed reflect some ideas from private techs or friends.
I would appreciate your helpful thoughts and ideas
