A/C job a flop ::rolleyes::

[Stu]

Yet another DIY job I've screwed up...

After getting it together yesterday, it had a bad leak. I've fixed it today, but it does not blow cold. Pressures are good, and no leaks, but 70 degree air and no condensation on the accumulator. Something is wrong.

Thoughts? I put in a new compressor, accumulator, orifice tube, and all new O-rings. Every ring was lubed, and the system was oiled prior to starting up.

How did you determine where thr leak was ?are you using r 12 or 134a?
Is this a conversion? What did you use to fill the system? Recharge kit
from store? Did you vacume the system for 30 minutes before charging?

[Stu]

I put dye it, and saw it coming from the threads on the top of the drier. Its o-ring was cut, and I replaced it.

It is R-134a straight, not a conversion if by conversion you mean it had R-12 in it originally. Off the factory it did, but it was converted years ago. I just used cans of R-134a from AutoZone.

The system was evacuated properly.

Why wouldn't the accumulator be beading up?

[Chachi]

the problem with using the cans from the store. When you add refrigerant you must
remove air at the same time giving the refrigerant
more room to flow in. Cans of R-134a from the store dosent let you do that..
what you need is a proper recharge machine. and unless you plan to do lots
of ac systems its not worth buying one..
I recomend going to a shop that has one and pay for the service. it will not cost as much cuz you
already have all the other stuff done.

I second that, using the right machine makes the cold air flow. In a way it's like flushing the system.

if the system was evacuated with a vacuum pump, that should be all you need. leave the vac pump on for a while tho, like hours.

Call up ron and have him hook ya up. I dont'e want to see 6 different ac repair gone bad threads. The tranny's were enough

[Stu]

Not being able to charge a system using a gauge set and store bought R-134a makes absolutely no sense. I know too many people that have done just what I have with great results.

I talked through this problem with a couple guys today and they are agreeing the compressor is probably shot. I'm gonna do a warranty refund and get a new compressor from RockAuto.com

[Blaze86Vic]

Man I would try gettin it done at the shop anyways. All that was said about gettin it done at the shop is true. All those people that have had great results, have you felt ther results in the blistering heat? Most the time they work fine untill it gets really hot, then it falls short where a shop job would not. Mine works great no matter how hot it gets, and my compressor is known to be shot. I pulled about an once of metal shaving out of my AC system last year. Re-charged it and it works great, how long before is ceases up...now that's another story. And my good is parked at idle putting out 41 degrees in the 96 degree day.

So are we establishing, on August 14th, 2005, here at GMN, that it impossible to do home A/C repairs? I am sure there is an entire industry that would like to know this fact!

What's next, no home engine repairs???

I'll let you guys know when it's fixed

Ewww, take a chill pill mang! Note the word MOST is used in there. And yes, if you think it unbelievable that a product off a shelf can not replace a $1000 shop machine then you need to reanalyze what is believable to you. They are meant to be a booster to a good system with low pressures anyways, not a system that has been opened.

Can you bore your block with a hand drill at home? Something to consider.

[RugerP97DC]

You can do anything at home! Well the block bore job mght be a *little* off!

I've seen those fancy machines. And they all have the same deep vane vacuum pump I've been using this whole time, with some fancy LEDs and control knobs. I am using the pro gauge set with real hoses. Not cheap crap people buy to add a little 134 to their system with. It charged to proper pressures and blows cool. It should be cold, but it's not.

This is superior tech?
