It sounds like the hoses are at under hood temp, if the valves where open they should be close to engine temp and then both valves would need to be open for all hoses to be at same temp. The valves are normally open and need power to close so you could do a quick check for that but it's probably more likely you have low refrigerant or something else going on like the previous poster is saying.
I guess you could turn the heat on (maybe even try one side at a time ) to do a sanity check on the hose temps and power applied.
