i have a 94 lx. i went to use the air conditioner and the pump kicks in, and it blew semi cool air. well i figured it needs recharged. took it to get recharged and picked it up about quitting time for the mechanic. i drove it home and it isnt any cooler than before. soeither they guy didnt recharge it or somthing else isscrewed up. any leads on what to look for so i can diagnose the problem. thanks

 

Perhaps a failing expansion valve, very dirty condensor blocking cooling air flow, or partially blocked evaporator.

A diagnosis requires measuring system hi/lo pressures w/ a manifold gauge set to determine whether compressor is actually compressing, expansion valve is metering refrigerant, or other problem.

good luck
