Generator slide lock

[cdat]

I have been trying for a week to get the gen slide lock to release, so far no luck at all. Yes, I've unscrewed the handle on the cable all the way.
Is there any way to access the generator compartment, or reach up and access the lock? The underside of the coach was sprayed with foam, so can't even see into the compartment. I'm assuming I can pull the radiator on the drivers side, or the air dryer on the passenger side, but hoping there is a another way, more then likely false hope.

Thanks
