check radiator for leaks
You need to check the vacuum lines for the a/c system for leaks, breaks and loose ones first.......
check to see if the evaporater is working or if its leaking, then check for leaks on ac lines going threw out ur engine bay
Condensation on AC lines can be prevented or managed effectively by properly insulating the lines to reduce temperature differences, ensuring proper ventilation and airflow around the lines, and maintaining the AC system regularly to prevent any leaks or issues that could lead to excess moisture buildup.
The 1984 Buick uses vacuum lines to change air flow from defroster to ac vents. Check the entire vacuum system for leaks.
v have to check the blower motor,ac pipe lines and cluster assembly
To check AC ducts for leaks, you can perform a visual inspection for any visible gaps or holes in the ductwork. You can also use a smoke pencil or infrared camera to detect air leaks. Another method is to pressurize the duct system and use a pressure gauge to measure any drop in pressure, indicating a leak.

If there are no leaks it should last indefinitely. I would recommend calling your local dealer and having them check for recalls. There is a large recall on one of the ac lines under the hood.
check for leaks, mostly check toward the rear and lines.
take it to a shop that recharges ac and get them to charge it and check for any leaks in the system. probably be about 80$
check all vacuum lines for leaks
