1996 Silverado A/C Problem

If refridgerant is low you definatly have a leak. You can use dye but I dont recomend it. All a/c lines are pretty much secure so 80% chance its not the lines. If you are pretty sure about your mechanical abilities you should be able to repair pretty easy. Look at all line connections and see if it is wet or oily. If it is you more than likely have found your leak. If not leaking there the other most common place would be your a/c compressor leaking. If so your looking at about 350.00 on parts. If you change compressorr it is a good idea to replace accumalator, and orfice tube as well. And if you do ask about a varible flow orfice tube. Air will blow 10-15 degrees colder at idle.
