Hello all.

New Blazer owner here. I recently purchased a 2004 4x4 Blazer w/ 135k mi. Love this truck. Just replaced all brake pads, rotors and calipers. Now on to A/C. It worked fine for the first two weeks then started blowing hot air. I recharged it and added some dye and found a leak. It is right where the compressor connects to the refrigerant hoses. It basically looks like the bracket that connects the hoses to the compressor is very slightly cracked at the right hose. It is a very small leak. Anything I can do seal this temporarily? Also what is that piece called that is cracked so I can replace it and where to get it? I appreciate any help! Here is a pic.

 

The block is part of the lines. No temporary fix. The larger diameter, low side hose, comes from the accumulator, and the smaller diameter, high side hose, goes to the condenser. Most auto parts stores either have the assembly, or can get it. Should come with the O rings too.
