Bad Expansion Valve?

I suspect that the expansion valve on my '87 900 isn't working properly. The high pressure line from the compressor to the condenser is hot, the return line from the condenser to the expansion valve is warm. The low pressure line from the evaporator to the compressor is also fairly warm, but not as warm as the line from the condenser to the expansion valve.
The vents blow air that is cooler than ambient, but not by much.
Is this typical of a bad expansion valve, or is it just low R134 level?
