If your evap is leaking freon, you would likely smell it inside the car. If no smell inside the car when A/C is on, then you may have to look elsewhere for the source of the leak.
There are many ways to try and trace an A/C leak, but for the novice, dye is probably the best way. As old as your car is, you could be looking at any number of different reasons:
- dryed/cracked seals/O-rings
- bad seals on compressor
- pending compressor failure if original
- worn/cracked hoses/tubes
- bad seal at schrader valves
- damaged/cracked condensor
See why I suggest you have it tested or test yourself (if you have equipment or a friend with same)? Some people go cheap test and get a bottle of R134A w/dye and cheap guage on it and fill with that first to see where leaks are. Others spend the big $$ for professional testing. Your option.
