Thanks for the help. Jumping the relay allowed me to get enough to plug the relay back in and charging up the system so I can monitor it. Ran it with the AC going for 20 min and it stayed cold with the pressure staying at roughly 40 psi so at least I know it shouldn't be a major leak.

I realize it's not ideal but for a quick diagnose of how bad a leak is, how harmful will it be running the compressor for 5 minutes while I force a can of refrigerant into it?

Thanks,this sounds way easier haha. I'm not trying to fill the system but get enough in there with some dye so I can see how bad of a leak I'm dealing with.

That was my secondary question. Can I fill it via the LP inlet even if the compressor isn't running. I assumed yes but everything I had been taught was to do it with it running full blast.

Looks like this one is 3 wires -- Any idea what pins should be jumped? I assume G/Y?

Thanks, I'll take a look. Looks like the photo you sent looks like HP to me - it's a smaller line. Either way, I know what to look for. The part you linked included the Transducer I linked, so I should be able to breadcrumb it.

Could this be it at #5 -- the A/C Pressure Transducer valve? Looks like a valve with a plug on the end on the LP side.

I don't think this is correct. This diagram is for a 2002 Dodge Neon. My Ram doesn't have this part

Dealer wants $1k to diagnose a leaked in my 2019 Rebel AC system. I have the YF and compatible dye but unsure where the actuator sensor is located. My system is completely empty and the compressor isn't kicking on due to zero pressure so I need to jump the connector. Anyone know where to...

You can refill with dye mixed into the YF. Use a black light flashlight to see where there are leaks. There's an actuator sensor that kicks on when the AC is running but without any pressure, that doesn't turn on. You need to jump the sensor with a paper clip/wire. Someone must know whar...

Now I'm questioning what the dealer did after getting my truck back. It was dropped off with working AC, now the system is completely empty and blowing hot air. With that being said, I want to charge it with dye but it's not kicking on due to no pressure. Where is the actuator sensor on this...

That's what the dealer is saying. They want to charge me $1k to diagnose if there's a leak. What's the hack everyone is talking about? As for the low refrigerant, the truck is 3 years old - no reason for it to have a leak at all imo

Right, I can definitely understand that. I think I'm more annoyed they want to charge me $1000 just to diagnose the issue (charge with dye and monitor for a leak).

Brought my 2019 Rebel in for a manifold repair and also complained about my poor AC performance. Unfortunately the truck is out of warranty (54k) but the AC has been trash for ages. Dealer is saying the AC systen is empty and they want $1000 to just diagnose the issue. I currently have a case...

Update for anyone following -- both exhaust manifolds being replaced under the powertrain warranty.

Thanks all. I'm going to bring it in under the assumption it's the cracked manifold. Also trying to get a good will repair approved for my trash AC the truck also has so pending that at the moment.

Right on. I'm new here - you mean physically PM @RamCares about getting a good will repair approved? haha.. Sorry slow to how to get that moving. I also have a very loud engine lifter tick im still not sure if its normal or part of a bigger manifold issue so I might try to have both looked...

Just in case, here's an update with a cold start from this morning. I still feel like it sounds like garbage but maybe it's just me trying to will myself into a new truck 🤣🤣

Thanks fellas. Worth bringing it in for or normal at this point?

Forgot to mention this is after the truck has warmed up.
