Kinda, but all cars are different in the procedure. It would be best for you to get the bleeding procedure for your particular car. Generally it's not very hard to do but some cards have bleeder nuts on the water pump, etc and a few require a tool or two. I bet if you google it you might find an answer for your car.
Here's a general primer:

but you should do yours according to your car's workshop manual.

2000 Saturn L100 A\C question

I am having trouble finding information on the O-rings used on the high and low pressure pipe at the evaporator. I went to an auto parts store and ordered an O-ring set for the A\C system, when I picked up the O-ring set there wasn't any information on which O-rings went where. I bought a Chilton's book but that was a dead end. I disconnected the high & low pipes and found what looks like a wiper instead of a O-ring. I replaced the so called wiper with the identical part in the new O-ring set but it did't hold pressure. I am at a lose as what to do, Please help.

'99 Ford Taurus, no A/C, no lights on panel

The above vehicle belongs to my girlfriend of which she informed me yesterday that the A/C is not working. I checked the panel in the car and noticed that there were not any lights working indication there was any power to it. I then went under the hood and checked every fuse box/fuse that I could find and no fuses were blown. Maybe it's a relay? I have not idea if those can be checked other than to replace each with a new one. She doesn't have any manual with an electrical schematic. If anyone knows where I can download a .pdf or other I'd be appreciative. I am experienced in electronics and electrical and have a VOM meter. One other thing, I did notice that the pulley on the compressor was not spinning with the belt. I'm not sure if it should spin if power is not applied to the clutch or not. I note this as a month ago she asked me what I could do about the squeaking belt. I was able to turn the set screw a turn or two to eliminate the squeak. Now I'm wondering if this is any way related to the A/C failure but it appears to be an electrical problem as I don't see any lights on the panel inside the vehicle. Now I'm not sure if there are any lights to light when you hit the A/C switch or not. Just can't remember. Thanks in advance for any help. Favors are returned.  Paul in Tampa

You can access factory Ford manuals at www.helminc.com There is a minimal charge for 2 day access on a particular vehicle, and you can print/download the pages/chapters you need, including electrical schematics.

Did you go to the Saturn dealer and get the specific O-rings for that car. I've found that's always much better than trying the aftermarket for specialized items. And it's cheaper in the end, both in terms of redos and my time.

imidazol97,
Is it importantly necessary to vaccuum the system after opening it up, before filling w/143?
I'm getting higher and higher low side pressure to the point that my AC compressor is running all the time now instead of cycling on/off (97 Chev Sub w/rear air), so am thinking about replacing the compressor. Everything is original, and has never had to been opened at this point. AC is somewhat cool now, but has been colder in the past.
Checked the autoparts store last weekend, and they have replacement compressors for couple hundred bucks, so seems like a simple swap out, assuming I don't need to pull a vaccuum. Haven't found a reasonably priced vaccuum pump. I'll probably start with the orifice first, as high pressure could also be caused by a restricted orifice (and they're only 3 bucks).
I've never vaccuumed in the past w/F12 when worked on systems years ago, just don't know if this is a 143 thing. Worst case I guess I cold just replace the parts, and then take it somewhere to vac and fill.

I found 1 auto parts dealer that could order the O-ring set all the other places I called said to bring in the O-ring and they would try to match it. It looks like I will try getting the parts from the dealer.

You haven't mentioned the pressure on the high side and what it's doing. I don't have an answer. I use the factory service manuals and work from the data and troubleshooting in there.

I have less than 25 PSI on both high and low sides. The problem with the system is a leak at the condenser connection; I am looking for a schematic to show the correct O-ring that is used to seal the connections at the condenser.
