If your HWH control box and solenoids are easily accessible, swap the solenoid from one of the other positions with the left front solenoid. If the problem follows the solenoid, you have isolated the problem.
As Bill/Diana suggested, download the manual and trouble shooting guide for your system and make good use of them in trouble shooting your situation too.
Do NOT swap solenoids. The o rings are damaged when pulling the solenoids. ALL you have to do is manually OPEN the bad jack solenoid and activate the pump. IF the jack extends your manual operation is OK. Then connect a voltmeter to the supply 2 wire harness to that solenoid. With the pump activated you should have 12 volts. If NOT, then you have either that solenoid fuse blown or a wiring problem. IF you DO have 12 volts and the jack extends with it manually open, your solenoid is BAD. Replace it. Doug
