Well sir, from your wording, I guess when you say "rear one will not move inward" that means, between the 2 motors that operate the slide the back motor, or the one closest to the rear of the coach is not bringing the slide in equally with the front motor, therefore the slide is binding going in. Is that right?
I would not go jacking around any with adjustments just yet. Let's address a few basics first.
A couple of things I'd check right off the bat:
You may not be getting enough power to both motors....so to start with
1) Make sure your batteries are fully charged
2) ALWAYS have your engine running before you try to bring the slides in or out
3) If you're plugged into shore power, stay plugged in until moving slides is complete
4) Check your weight on the slide itself. In other words, before you try to move the slide, make sure the slide isn't overloaded with stuff, people, etc.
5) You may have to crawl under the coach and manually crank in that rear motor some to get both rails equal again first. See your manual
6) Make sure the floor is clean and no obstructions. Once this is done—while the slide is still out—take some baby powder and sprinkle it all along the front of the slide on the floor about 4" - 6" out from the edge of the slide. Do this a couple of three times as you go on trips. Over time, the baby powder will get dragged under where the slides make contact with the floor and make that area real slick creating less friction which will be easier on the motors.
Hopefully some of these things will cure your situation. You may also have to re-sync your slide motors now that they've gotten out of whack. Your manual will describe the procedure for your slide system.
Please follow up and update us on how you finally solved this issue for our future reference.
BTW...do yourself and us a favor by putting your MH and Toad information into your signature
This will really help in all your future posts
, so you won't have to type it in each time.
You do this by:
1) Going to the top of this page and click the top left tab named “User CP”
2) Look at the menu on the left and scroll down to “Settings & Options” and click “Edit Signature”
3) In that text box type all the information about your MH, Year, model, length, mileage, any aftermarket extras installed, your toad and so on. You’ll be limited to 3 lines unless you become a IRV2 supporter.
signing up and becoming a IRV2 supporter. It’s a small way to give back to what we all reap here.
Good luck my friend.
