Default 1998 HVAC Losing Charge

As stated, I put a can of 134a in it with leak detector and for the life of me cannot find where its leaking. Before I'd put a can in and it'd be ice cold and in about a week hot air again. What are the chances its leaking from the evaporator? Are there any other places you suggest I look?

Have you checked around the compressor shaft?If the leak is there you will notice a lot of moisture and dirt accumulating around it.The evaporator could be the culprit also.Check it by inserting the sniffer into one of the vents and see if it picks up anything.

well, unfortunately I don't have a sniffer. I have the UV light. I'm going to go jack the car up and see if I can find anything underneath.

Buy a new compressor. Leak(s) are inside the compressor.
Read the bottom of this:
