Since the search on LS1tech seems to be a bit broken (can't search just this section, only the entire site), could someone give me an idea what I need to do to use the stock 5.3l AC compressor with older AC system? What sensors/switches does the PCM need to operate the variable AC compressor, if any? Will I need to change the condenser to a larger unit, since this will be a R12 to R134a conversion? Does the orifice tube need to be changed for a different type? The stock AC system on my Jeep is thermostatically controlled and used a york compressor, and had a low pressure limit switch. I'd appreciate any info or experiences you guys have on this topic.



TIA,

What year is your setup(5.3)? Are you using the pcm for the 5.3?

It is a bone stock '99 5.3l. The only change to the PCM is the removal of VATS.

Not sure about a way for you to hook it up... but for the search check this out.

More specifically, to search in a particular forum:
"To search within a specific forum:
1. Get the forum id number. (Hover over the forum, and look for the number in the status bar as above)
2. In the search box, type forumid:<number>.
3. As above, you then specify the stuff you want to find in the posts. ie. forumid:45 fuel injectors"

Might help you find some answers...

Thank you for that information! I rarely go anywhere other than Conversion & Hybrid section, so I would have never seen that.
