Try this.
Shut off the air to all of the bays. If you still are not getting fluid to bays 1 and 3, then you need further check the fluid solenoid for each of these bays. A solenoid is a magnet that lifts the inside plunger. Put the bay on, then touch each solenoid with a light screwdriver to be sure it is magnetized. If it is not magnetized when the foam switch is on then the solenoid is not getting juice. If the solenoid is magnetized then the plunger inside is not going up and down. Note that a solenoid "rarely" goes bad. Most normally it is in the valve. If both of these are ok then you have an obstruction between the solenoid and the bay. Are there any check valves in between? Sounds like your getting air and no fluid. If check valves enroute was bad then there would probably also not get air. My bet is the plunger in the fluid solenoid.

Good luck
