Moto-massage help

[96SC]

We have an '07 Vanguard with both the single and dual moto-massage.  Recently we've noticed that neither massage will operate.  Both systems have full 'jet' power but the mechanics don't travel up and down, they stay at the bottom position.  I can manually move each up and down but when released they fall back to the bottom.
I have reduced the water flow to the neck massage to see if that helps but doesn't.  We have also tried to operate them with only one set of spa jets (there are two sets) running without any luck.
Anyone have a suggestion what may have happend or what we can do?
Thanks
I have also cleaned the filters.

Have you ever replaced the filters?  Did you try running without the filters...just as a test?

I took out the filters and had the same no action results.

I was just searching through the site for something that might represent your problem. Here is one thread to review.

And another. Is there possibly a leak in the tubes? Check this out:

Many times when we have taken a HS in on trade
we find that we have to run up the street and buy
a new moto assembly to replace the defective one
before we resell the spa.  It's a fairly simple job.
