95 850 Turbo Wagon

First of all I know there a million a/c posts, I know cause I think I read them all BUT I cannot find anything quite like my problem. I hate posting about a problem that has been answered/discussed so often. Forgive me.

Ok, Last fall I replaced my siezed up compressor with a used one, before the compressor siezed the a/c system worked perfectly. I charged up the "new used" compressor but it only clicked on for about 2-3 seconds then would shut off for 5 seconds then on, off...etc. It was cold outside so I wasn't sure if it was cooling the air or not. So, now that it's warm out I turned it on and it still does the same thing but the air temp from the vents does not cool at all. I opened the hood, I have a full charge, only one hose leading into the firewall is cool and the other is warm from the engine. I jumped the low side pressure sensor for about 2 minutes which turned the comp. on until I un- jumped it. The one hose got colder but the other-nothing happened and still no cooler air from the vents.

Related or unrelated-over the winter the car began a terrible sounding rattle, I cannot tell exactly where it is coming from but I'm really thinking it it the compressor as the comp. hoses/lines vibrate alot and actually loosened the condenser bracket to the point the condenser was practically hanging by the lines (fixed this though)

I've read about the reshimming job which I will do but only if I can be 90% convinced this is the problem. I'd hate to put it all back together and still have the same problem. Otherwise should I replace the compressor?. I can get a rebuilt one for near half the price of new. Could something else be the culprit?

Any Thoughts???

 

How did you charge it?
Did you replace the orface tube at the same time?

 

I charged it using the "quest recharge kit" It contains oil and gas together, thats the funny thing-it didn't even take the entire can maybe only 3/4. I figured I'd have to put in one can of that plus a can of straight gas but it wouldn't take it. Could there be air in the system which needs removed?

 

Problem solved! I guess the charging procedure from the can is not a good idea when the compressor has been completely emptied. I took the car to get the system evacuated and recharged and I now have ice cold air! WHEW!!

 

OK glad all is good now.

 

A bottle of ice-cold beer would be a nice finish-up.
