I have a 1995 sundance calypso spa. got from a friend who had it for a couple years. He got it from his perants when they upgraded.
The jets in the lounger do not work. When he had the jets had low flow.
I opened the air inlet and twisted the jets to turn them on. I don't hear any air coming from the air lnlet like i do for the other jets.
I removed the air hose from the air manifold and blew in to it and did hear water bubbling in the spa.
any suggestions?

Check plumbing for kinks (if it is not buried in foam). Sometimes pipes can kink in older spas which can cause flow problems. This could be either the air lines, or more likely the water lines that feed this seat.

A lot of Sundance tubs have diverter valves, usually near the controls, that will divert all the water flow from one section of the tub to the other. If you only have one pump this may be what you're experiencing. Turn the pump on high and check all the knobs along the top of the tub to see if any of them do more than just allow air in.

If you have a second jet pump that operates that side of the tub it may be air locked or have another issue.
