HWH Series 310 Problems

I have a 2002 Winnebago 32 foot Adventurer on a W22 Workhorse Chassis. I now have the vehicle in storage and when preparing to retract the jacks there was no power to the HWH control panel. I checked the fuses at the HWH box and in the dash area.
Coincidently the driver door power window, heated power mirrors are also inop. Unable to locate fuses that control those systems. Anyone know of locations for fuses or other issues that might cause these problems?
I am currently waiting for a call from HWH technicians but from what I see on the site it sometimes takes a long time to get a response. Thanks Jerry

This link to fuse panels may not be the same as yours but give it a try.
Near your HWH pump there is a fuse on line to pump in black fuse holder.
Under your front bumper drivers side WH has a ground post welded to frame of chassis on this ground post all your white wires from solenoids go to it make sure the ring wire connectors are clean and tight.
If loose nut take off wires clean and use di-electric grease and a star washer to keep nut tight on ground bolt.

Thanks for the quick response. I will check out the fuse at the pump location. I did check the ones listed in your link and they all had continuity. Thanks Jerry

Well, we finally resolved the problem with the HWH system. We found after several hours of reviewing the Winnebago wiring schematics and tracing wires we learned they had tied many systems together. We decided to check all of the fuses. The fuse for the radio was blown. This fuse affected (the ones we were aware of) the Defrost fans, Driver door power window, Heated power mirrors, HWH system and the Door step. Also, the radio would work on house power but not on the engine side.
Anyway, it's all good now. Hope this information will help someone in the future. Jerry
