You just inject the dye to the a/c line (low pressure side) or you can buy R134A that is pre-mixed with the dye. Just shine the black light around the engine bay especially near the a/c system components and if there is a leak you will see a greenish-yellowish light appearing from the dye in the UV light

Check the plug connections on the back of the head unit, especially if you have removed your center bezel for any reason. I had trouble with my a/c working intermitantly and took it to an a/c guy. He checked everything and said the head unit was probably bad. I got a new (used) head unit off eBay, and when I went to swap it out I found one of the connections on the back wasn't snapped in securely. My fault, when I had bezel off for radio work. Pushed on till snap, a/c works perfect. Luckily the ebay unit was only $36, so not a very costly mistake.

I got that on my lunch break, came with pressure gauge nozzle, two tanks, one with dye in it and the uv light. And then I got the Haynes manual, but for this is shows the hemi of course, but the low pressure is right next to the Coolant res right? If this doesnt I'll check that dashboard too like he said because I did disconnect my plate

Yeah sounds good. Also shine the light under the dashboard in the foot compartments where the blowers are..how much was the kit with the black light? Yeah low side I believe is there..the low one is the line with a bigger diameter and the high side is the slimmer one. It all makes sense..the less volume, the less pressure

$50 but the nozzle doesn't fit there, can I put it on the accumulator?

Do you mean in front of your radiator? The one that looks like a radiator is your condenser. Where is it leaking on there? Could just be where the lines bolt on to it? If it is from the condenser itself then I don't think it can be fixed. I believe those are aluminum and are very tricky to weld.

Yes, the AC is not connected to the engine radiator. It is a condenser and it looks like a radiator. but is just for the AC. If that is leaking from the condenser itself, you'd be better off buying a new one than repairing it. Also check the connections like sleds suggested. You can get a new condenser off rock auto for like $66.

The condenser is very easy to replace, mine has been replaced, and I did one for a buddy who accidentally cut through his doing a body lift... >.>. If the lines going to/from the condenser are leaking then youd replace those, but if its your actual condenser, just replace it, unbolt the old and bolt up the new one, add some freon and youre golden!
