Solenoids behind Pass Head Light 4369

[RJ77]

Does anyone know what those solenoids control located behind passenger headlight. I noticed residual leakage on ground when it is parked.

Probably for the jacks and your Full Wall Slide. Should be a tank with dipstick to check the fluid level. The FWS needs to be in and the jacks retracted when checking the fluid.

Those are for your jacks. Try snugging them up with your fingers. It’s not uncommon to have some residual fluid around them, just not serious drips. Clean the area with a bit of degreaser like 409 and then recheck after a couple of usages.
