Check to make sure that power was available to the switch , it may be as simple as the switch , look in the manual the breaker may be tripped if there is no power to the switch. breakers a little hard to see if tripped so look twice .If the limit on the latches is malfuntioning / stuck whatever the unit wont slide out dont know if same would apply for slide in , maybe they moved ect when unit out and safety defeating it to slide in as that would be bad sliding in if latches where partly out. I also have 2004 slide out. If I can be of further help please contact. Industrial electrician so hopefully capable of electric help.
