01 prizm, AC blowing not-so-col air

[dizwiz24]

Im having an issue with my 01 prizm AC. Its blowing not-so-cold air. The A/C light does come on - like it should, when I turn the fan switch on w/ AC button depressed. The air is kind of cooler, but not really much.

I suspect a leak is somewhere.

Since prizms are kind of quirky (I believe the A/C is different than on the corollas), I figured Id ask here to see if anyone knows what might be my problem....


The history of the car is as follows:
1. I buy car in May 08. AC blows ice cold at time of sale. I suspect the owner just charged it right before my test drive.

2. June 08. I replace engine (due to engine consumption). I go to bleed A/C lines and notice that theres 0 pressure in the system.

3. July 08. After I replace engine, I send it to a trusted mechanic to recharge system. (yes, I am comfortable replacing an engine, but not comfortable recharging an AC system).

4. A/C blows cold (although not ice cold) after mechanic recharges system.

5. June 2009, A/C is not very cold, theres very little pressure in system.

yes, you have a leak. you need to have it repaired and the system recharged. a dye kit will help you find it, you can google that.
