About 3/4 the way in the green. But whats wierd is when i push in the valve core looking thing nothing but air comes out.

 

Ok i checked the blend door. Its operating like it needs too. Im still stumped...

 

It must be low or high on freon, unless something is clogged. Mine had to work through and worked better as time went on, once I got the right amount of freon in.

 

First, be careful when working with A/C components - the high pressures and extreme temperatures must be respected. suggest eye and hand protection as a minimum.

Suggest to get a real set of gauges and check the high and low sides. 3/4 in the green is not a measurement, thus the previous paragraph of caution / concern. Given the conversion - the compressor may have shelled out.

Another possibility is the blend door - I had to adjust the cable clamp on mine, as the door wasn't sealing off in the cool position.

If you emptied the system- may have gotten air introduced. System needs to be pulled down with vacuum to remove the air and related moisture that may freeze up.

 

Damn, that's right. Did you vacuum it first?

 

No. Dont have one of those

 

If you want it cold it needs to be vacuumed. $20ish at Harbor Freight but you need an air compressor to run it.

 

I have an air compressor. I dont guess i could get my wife to suck on the connector real hard? Lol. So does it sound like thats all it needs?

 

From what you said everything seems to be working properly. Right now air is taking up space that needs to be occupied by freon, and you have excessive moisture in the system.

 

IMHO it really takes a professional with the proper tools to check out and repair automotive A/C. For example, nobody mentioned the orifice tube, also known as the expansion valve. You can have a full charge, the compressor, dryer, evaporator, heater doors etc., are working right but if the orifice tube isn't working, no or very little cooling happens. The clue, if I remember correctly, is that the low-side hose connections around the tube get very cold, might even freeze. Or maybe it's the high side hoses. Anyway, I'm not an A/C professional.
The real reasons a pro should take care of it are
1) The tools are expensive. If you're a backyard mechanic, will you use them enough to justify the expense? Do you know how to use them? It's easy enough to add a can of refrigerant but what if that's not what's wrong? You might be causing more trouble and expense instead of solving the problem. That's a false economy--you end up spending more in the long run.
2) It might be illegal to do it yourself. In most states you have to recover R12 or R134 (the newer refrigerant), not just let it vent into the atmosphere. This requires VERY expensive equipment. Of course nobody really checks up on backyard mechanics to see if they're doing illegal A/C work, but it's still illegal. Big fine. R-12 supposedly damages the ozone layer and R-134 causes cancer... maybe. Or maybe DuPont's patent is just running out, who knows?
This is not to say that I've never added a can or two of refrigerant myself. I have and probably will again. But I almost always end up at my mechanic's shop to get the problem fixed right. Maybe it's just me.
