Pull a vacuum and boil the moister out. It must pull at least 20" or closer to 30". You can also use nitrogen to check for leaks, but you would have to recover the system and fill it. Then check for leaks. I haven’t had much luck with "sniffer" I like the dye as it has always worked for me. But the easiest way to look for a leak is to look for an accumulation of dust around all fittings, sensors and compressor seals. The a/c system switches are a common point of frailer, but the fact that you can command you a/c clutch and still have hot air would leave me to believe that your system is low. DO NOT run a compressor with low refrigerant. All the oil will be pumped out and the compressor will lock up.

Took the truck to an ac shop last Friday. They said they did an evac and refill then added dye. Couldnt find any leaks and ac was blowing cold. I go to pick it up on Sat. ( they are closed) and the damn ac dont work. Sooo I call up Monday and drop it off that evening. He checked it over real good and he says the evaporator is leaking
Remember this thread ---->Dewmanshu"s ac gremlins <----
Yeah, that may be me in a couple of weeks. Also just to give you a rundown of what this could cost.
Evac a refill w/dye- $145 ( shouldnt they have done a leak test first)
Evaporator- $370
Labor- $450
I dont have to pay the $145 again no matter if I replace the evaporator or they do. But, if I do it, I have to be back for the refill by 30 days.
What would you guys do in this situation?

if the evaporator is leaking id have it fixed, or if you are up to it fix it yourself.
i cant say what id do because i have a vacuum pump, a/c manifold gauges and fittings to put the freon and dye in so id do the putting freon in but finding/fixing leaks is what i hate, especially small ones. i wouldnt even think about replacing the evaporator.

Welllllllllll.............
I am shoulder deep into trying to replace my evaporator. This absolutely sucks. I spent the better part of the day taking my front seats, console and dash apart. Its stripped down to the frame work of the dash. Looking at were the evaporator should be in the ......"big black box"........ sorry dont know what it is called, it looks like I either unbolt the bottom of the box to access the evaporator. Or I must be able to take the box out or something.
If anyone has done this or seen it done before please post up. I could use the help. I will post some pictures in the morning of what I am looking at (forgot camera in garage).
I'd also like to thank TorqueWrench for getting me prices and part numbers for what I needed. Although....... if he hadn't pointed me in the right direction, I wouldn't be in this mess right now. Damn you TorqueWrench!!!!!
JK its all good

Just shoot yourself in the hand that you'd use to do all the work now. Torque_Wrench will go out his way for you!

Well I got it out. The evaporator does have a split in it. I can see why the guy wanted so much for labor.
Here is a pic. Hopefully it will be all back together by mid week.

Also I was wondering if you can replace the cabin airfilters after everything is all back together? They are really dirty and I cant get new ones till Tuesday. It looks like you can replace them through a small access door from the bottom.
