a\c lines on 94

Ok. i got a 94 taurus. 2 years ago my brother went out for a joyride in a snowstorm, then hit a curb. Had to replace balljoints, control arm, etc. Now. ever since then, the a/c hasnt worked. the compressor kicks in and all, but no cold air, warm infact. Now, a friend of mine had the same problem and said he took it to the shop, and they found some crimped lines underneath the car. Now, i figure i might have that same problem. Can anyone tell me where the lines are? Where should i look??

Follow the lines from the condenser and the compressor.
