The A/C quit on the Tahoe. Luckily I had dye in the system from when I replaced the hose seals on the compressor earlier this year. Found the passenger side of the condenser is glowing green. I can get replacement condensers, but apparently most of them are a parallel flow design instead of the factory serpentine design and don’t fit the trucks quite right. You need different rubber blocks to make them fit and they are discontinued by GM. I found a set on eBay that will cost about $70 shipped. It looks like I can get a serpentine design condenser off of Rock Auto still for $70 I think it was. I understand that parallel flow cools better which would be nice in a big black box without rear air on a hot summer day, but is it worth the hassle and cost of conversion? Also, regardless of the condenser I go with, which orifice tube should I go with. BTW, yes I will be replacing the accumulator while I do this repair. Thanks in advance for any info.
