Best Answer

The 99 Chevy Astro uses the refrigerant R-134a. You can purchase R-134a and all the tools to recharge your A/C system from any auto parts store, most department stores, some warehouse stores, and even at convenience/gas stations.

Make sure to use a high side pressure gauge and thermometer to ensure a proper charge. Follow the directions included with the tools.

The problem is that refrigerant R-134a does not 'go bad', it leaks out from a part of the system. You should determine where the leak is and fix it, you will usually see oil residue where the leak is located. A very common place on Chevy/GM vehicles to leak is the A/C compressor. These can be replaced from after-market suppliers.
