I'm talking about a consistent drip. After start up, when the system pressurizes, there is a constant dripping from the underside of that box, hits and rolls down the wheel well right onto the leaf spring, nonstop. It's gotta be more than drainage right?

Funny though, that's exactly what my service adviser at the dealer told me over the phone.

 

As stated numerous times, normal. That's how it works. Warm air contacts the cold evaporator, water condenses off of it, and drains from the system. The more humid the air and the more air that flows through the evaporator the more water you will see drain.

Your air conditioner at home does the same thing.

The compressor should not run continuously, it cycles, and improves mileage not hurts it.

 

Okay Okay. I don't mean to be a hardhead about this, it's just that it's not happened before. I know I've only had the truck for 4 months, and maybe just not experienced this before. Thank you all though for the input.

 

LOL, didn't mean to sound mean.

Kinda sounded that way now that I read what I wrote.

Not mean. To the point and what I needed to hear.
Cheers.

 

Harlen, When you have the setting on the feet and face, that is an air conditioner position. Defrost, defrost and foot and I think even just foot will also run the system. If you switch it to just face, it blows outside air without running the system.

Like a few of you, I have noticed a pinhole leak coming from my evaporator too (Top line). My A/C was taking longer than usual to cool, and wasn't super cold, so I figured it needed a recharge. I put a gauge on it, and it was running 30psi (85 degrees ambient), which is 15-25psi low for that temperature. I then proceeded to add a can of refridgerant/oil/booster. It made it up to 35psi and took the whole can, but never got any higher. Once I pulled the can and the gauge, I noticed that the line was bubbling where it goes into the plastic housing. I quick touch of the finger confirmed that it was refridgerant (Slippery can red/pink colored).

With an evaporator replacement (They always recommend replacing the drier too when the system is opened), vaccuum and recharge, my local trusted shop wants $585. The Evap is only around $100 from auto parts stores, but I don't have the tools for the vaccuum and I like warranties!

 

its normal for there to be a hissing noise, the compressor pumps up a reservoir to a set pressure, then its slowly bleeds off through an orfice into the evaporator. as the pressure drops the compressor kicks back in. most modern A/C systems have a low pressure switch, if the freon has leaked out it won't allow the clutch to kick, this saves you from destroying the compressor for a leak. so if you look under the hood with the a/c on and the engine running and the clutch is engaged you know you have freon. which means you can't have a leak

 

I have been watching mine for the past week or so now that the temps here are around 100 degrees. I have no issues, the air conditioning works just fine. I get the condesation drip on the passenger side which is normal. Nitrogen validated the hissing noise which makes sense.

 

so how come I have the same situation and I end up having to charge the low side and loose ac til I do.
