Not sure if the jacks have fuses but there are two types of jacks (well 3 but only two apply to you) Electric and hydraulic.

Hydraulic jacks retract by the power of a spring. THe pump is not needed to retract them.. Just open the valves, and up they go.

Down needs the pump.

Fuel pump. Filter & fuel gauge sensor are all new..

I'm not sure on the Jack's which one they are. It has big hydraulic tank infrastructure and of driver side. The levers and box are beside the driver seat. U turn the box on & it works & shows which side needs to be adjusted. U lock the levers put & nothing happens but when u use the center lever that adjusts which Jack's go up & down there is a click. So not sure

Does your MH have auto park? If it does the transmission does not have a parking pall, the auto park and parking brake are the same thing, it is hydraulically operated.

If you have the 454 engine you probably have the P-30 chassis and the auto park system and the brake drums at the end of the transmission need to be adjusted if your hydraulic pump is working. Can you hear the pump coming on when you put the transmission in park? Verify you have the P-30 chassis. Do you have the HWH 200 series hydraulic levelers? If so check the fuse in the the top plate next to the joy stick and see if it is blown.

With the P30 chassis the park brake needs the be applied before the jacks will function.

Thanks guys.. it is the p-30 chassis. I'm not sure about the type of hydraulics it has on it but the top plate does have a fuse & yes it will not work if the parking break is not engaged... this all shows on the top plate so I know I have the parking break engaged & the fuse is working because I have power to the top plate & the red light is on & its showing which way to adjust the rv. But when I press the 2 levers down the Jack's do not come down??? Now if i use the center lever and move it around i can hear the click sound like it working but the Jack's havent come down.
So fuse is good & parking break is engaged

You describe the HWH 200 series jack levelers. Unscrew the knobs on the 3 control levers and unscrew the 4 screws holding the plate to the floor and lift off. Use a vacuum and suction debris out from around the contact ring surface. Debris interferes with making the electrical contact for jack engagement. For your own learning, go the HWH website and download the manual for your system, it is invaluable in troubleshooting. Best of luck.

Thanks guys. I actually have the manual from hwh. I went looking through all the stuff I had. I did that exact thing & still nothing. So when I turn the key on & engage the parking break. Then I press the on button. The red light comes on & I have a yellow light that shows the front passenger side needs to be raised. When I flip the levers nothing happens. I dont hear anything. When i move the center lever i hear a click but that is all. Is this a bad pump? How can i test it? If it was a fuse I dont think the lights would work or i would hear a clicking sound when activating the lever.
Also is there a way yo remove the center level toggle? So I can get to the plate & cleaned it... one video showed an allen wrench but mine does not have an allen screw inside it
