Not normal for that to happen but the jet faces on the two back jets may be turned off or down.
Try turning the face of the jet clockwise and see if you get more water flow out of each jet.

This sounds like the air switch in the motor is not working properly. You will need to remove the pump from under the tub to access the air switch located in a housing on the motor.

Replacement Air Switch will cost you about $20

The problem you are experiencing is common to many jetted bathtubs.It is a result of dried bathing water in the tub. There are a couple of solutions to resolve this ongoing problem.

1. Use your tub more frequently as the water will not have time to fester in the pipes.
2. Use a cleaning solution made for cleaning the pipes on jetted bathtubs once every three months.

sounds like maybe the jet faces are turned off. see if they turn one way or the other and they may open and spew water out for you.

It depends on the brand of jet and tub, if it is a gold or silver trim ring, they will generally pry off with a screwdriver, just be careful not to damage the tub when doing so. When prying, move the screwdriver around the jet an inch at a time, just like opening a can of paint. Some rings will screw on, but most just pry off.

You can adjust the jets by moving the center of the jet around, if the center does not move, it is not adjustable, some jets have a pressure adjustment by twisting the center of the jet left to right. No manual necessary for this.

Jet trim usually unthread counter clockwise out of the wall fitting
