[3.2 CAB]

To begin, do you have any idea of what type of refrigerant is in your A/C system?

If you have a friend that has a vacuum pump, they may also have 2 or 3 empty jugs, for the type of refrigerant that is in your cars system. They could run a vacuum on the empty jugs for you, and let you take them home, or where ever the car is located and then all you would have to do is then connect one of the tanks to your A/C system, and let the vacuum that the jug is under, draw the refrigerant into the jug. Repeat as needed with the other jugs. This is NOT a perfect or ideal set-up to use, but it will work to evacuate your system of whatever refrigerant is in it. You could then take the jugs back to your friends place, and let them run it into their recovery system. Most people that have recovery systems need to verify just what type of refrigerant it is, before they take a chance and contaminate their R12 with 134A, or other types of mismatched refrigerants. Heck, it may even have freeze12, or some other questionable product that would not be wanted to be mixed.

As I stated, this process is NOT an ideal method, but will work fairly well, if, you have access to the small amount of equipment needed. Good luck!! Tony.
