Then maybe it could have been the brake/clutch fluid leaking from the inside but the reservoir was full and the paint from the floorboard had no damage. Therefore the last one must be the AC refrigerant. However, I have a problem believing the evaporator has a leak. Are there any other places inside the cabin where the AC refrigerant might leak other than the evaporator.
I will be able to see my TJ in 2 months and would like the purchase the parts in the U.S. for it is cheaper.
The only place the refrigerant travels in the cabin is the evaporator. I don't think there're any other places it could come from inside the cabin.
Fwiw, mine leaked...they're a kind of a PITA to replace, you have to take out the dash, but overall not that bad of a job I guess. If you replace it, I would highly suggest replacing the heater core at the same time.
Edit: if you can afford the mopar stuff, I would go that route, some aftermarket stuff doesn't fit as well in the hvac housing
