If its a Shwintek slide, then there are two (2) motors, one on each side. Then there is an electronic control module hidden inside a cupboard or cabinetsomehere. On my ST25RB its under lower right cabinet door under LCD TV. The module syncronizes both motors to operate together so both run at same speed to retract or extract slide. Also has some troubleshootingfeatures to tell you what the problem is when slide fails to operate, (LED lights flashing codes....which you must count). The video links I sent in earlier post shows how this works.
As for the awning, that is made by A&E Awnings I believe (division of Dometic - the refrigerator/AC guys). My ST25RB manuals package came with instructions by Dometic on where motor located (frontside of awning) & how to replace & disengage if it fails. You can probably do a "YouTube" search on repairs video or how to raise or lower in case of failure.
Hope this helps.......Happy camping!
