Hello, Deborah -

I am not finding an online repair manual for the Brookstone Shiatsu Foot Massager, model 257097.

If you have not already done so, you could call or email the Brookstone Customer Care phone number and ask a representative about the availabilty of such a manual or a location where you can take or send your massager for repair.

This is the link to the Brookstone Contact Us web page:
http://www.brookstone.com/contact

The phone number is in the upper right corner of the page, or you can complete the form there to send an email.

Note: A manual I found online (PDF document, Adobe Acrobat Reader software needed - free) for a different Brookstone foot massager, model BR-7100A, gives the following warning:
(Quote)
To avoid the risk of electric shock, do not disassemble or attempt to repair the unit. Incorrect repair can cause risk of electric shock or injury to persons when unit is used.

I assume this foot massager is a dealer installed item on your unknown car, or you have posted the question in the wrong section.

Google it.

My foot massager is making a grinding noise. I go through a lot of these machines because I have neuropathy and it is the only thing that really helps. Has anybody got a fix for this? Thank you very much

Sounds like the cable to foot massager is trapped in the levers. Turn it on its side and check. Unplug it first.

try typing what you want into your search engine ie, user's manual" for King king USA Big Foot Infrared Foot and calf massager. you might be pleasantly surprised
