3500 Exp. engine hatch not working.

[giff1]

On my 2000 3500 Express, the starboard engine hatch ram actuator stopped working. The port ram does operate up and down when the switch is pressed.
I have read on this site about the same problem, but on a 3500 open that had bad relay switches. On the 3500 Open, the relays were behind the helm.
Does the Express have the same relay switches and where are they located? What would the relay switch look like? How do it trouble shoot this ram actuator. Thanks.

I don't know for sure where the relays would be in a 35 express, but I would expect them to be behind the dash.  There will be 4 of them lined up next to each other.  Generically this is what they would look like

The 4 relays are set up in a 'reversing' configuration.  Each ram has two wires, so 4 wires total for the two rams.  Each of these 4 wires gets its own relay, so if one of the 4 relays stops working, you would get the symptoms you describe.  Of course it could also be the ram itself, as well as a tripped breaker, or disconnected wire.  A volt meter and 15 minutes can tell you the root cause.
