Yeah you can replace the valve without pulling the dash if you hate yourself, your car, and life in general. You sure do get better access to everything once the dash is off though. Anytime I see a procedure that requires several crows foot wrenches and an amateur contortionist to complete, I try to look for a way to make it less painful. Also he's going on there to check the evap anyway. Removing the cruise amplifier to get to the brake switch was one of the worst experiences I have ever been through and that was with the seat unbolted. I am really not looking forward to pulling the column because the power adjustment is not working.Just to clarify, you must pull the dash to replace the evaporator, not the expansion valve.
