The functionality of "Manufacturer" link can't be related to "Carousel" module. They are apples and oranges. They can't effect each other. It doesn't make any sense.
And the problem with the "Manufacturer Link" has nothing to do with jQuery. It is much more serious thing.
If there is a jQuery issue, then you will see red warning in the Firebug Console and the jQuery dependent effects won't work (for example; drop-down shopping cart won't slide-down when mouse-hovered).
Do you see a RED WARNING in the console window of Firebug? I thought i have fixed it already. There shouldn't be any RED WARNING. In what URL exactly you are seeing the jQuery Error (RED WARNING)
Also don't attempt to enable the jQuery FIX ever. That option is not for your website. It is for very rare situations.
For example, in this page:
www.union-bike.com/servicios/tienda-online
Where the carousel module is being used, there is no jQuery conflict.

TIP: If you want to publish only 1 product, then don't use the Carousel Module, it will increase the page loading time. Instead, use the official VM - Product Module.
Finally, the Product Carousel Module is not a responsive module. And wasn't developed for responsive layouts. (unless you use the vertical-theme). Because with the "vertical-theme" the width of the module is already small and suitable for smartphones. But if you use horizontal-themes, then there will be layout corruption. Because the module width won't be resized automatically based on the device resolution.
