Rear suspension won't dump

This is my panel. I don't find solenoid fuse

 

check F63

 

and f64

 

Yea their good. I put new ones just incase.

 

Make sure they have power

 

With a test light

 

Did you find the fix

 

Fix?

 

F63 fuse. If both dump and fifth-wheel not work i would check that fuse first

 

If not fuse then solenoid switch down by transmission. There is a row of 4 or 5 also engine fan on the same bank of solenoids. I had to replace the whole row of them when my suspension dump quit and fan clutch operation was erratic last year on my '04
