ac = problems
all posts are great info !! do it all! I would suggest - as likely the evaporator was =coroded inside- to flush the entire system out with a flushing agent too! prior to replaving any driers.Likely also will need a new compressor. dont be cheap as if system is coroded?? that stuff is already in the compressor!!

|LATECH||Ideally you would flush it out and get it clean. Synthetic PAG mixes with ALL oils , that takes all the worry out. get system clean as possible, and assemble. It will be good to go.|

|LATECH||You would be suprised how many people dont know about running the HVAC on Recirc. If only they would read the owners manual...|

|mitmaks||Took my gauges to work today to check co-workers truck. He was complaining that it takes forever to cool off air inside. First thing I've noticed is his recirculate wasn't on. Turned it on and temp went to ~40 like it should|

|mitmaks||Now just waiting for a/c dryer for my mazda. Should be here this weekend. I haven't had working A/C on it since I've owned it. I just hope compressor will work and PAG oil won't mess it up.|

What I did with oil is I've dumped 1/2 in the dryer and then dumped some in the yellow hose/recharge hose. Opened can and bled it to make sure there was no air and then I've opened low pressure side and charged it that way.
It didn't want to cool off much (thermometer in the vent) stayed at ~60-65F and then I drove it around and I guess it stabilized and now its ~45F like its supposed to.

Not sure why, maybe to help redistribute oil, dunno.
Everyone charges through the low side , except maybe the factory where they have the equiptment to dump a liquid charge in the high side on the assembly line. Its fast that way, and the charge is accurate, but I am sure it aint cheap.
Charge through the low side .
I allways turn a compressor after I install one, to make sure the oil redistributes itself, to keep the compressor from hydrolocking and breaking it. Usually I rotate it 12 -15 revolutions , with a socket on the clutch nut. If there is no nut , i turn it by its face. just as long as you turn it, you'll be sure the compressor doesnt get damaged.
You better watch out, you'll be an old AC pro before you know it,

I've been reading factory repair manuals and it states when charging I should open high-pressure side of manifold and charge until low-pressure side reading is at 10psi. Then you check for leaks and it there's no leaks you're supposed to charge with the half of regular amount of refrigerant. This is supposed to be with engine off.
I've always though you only charge on low side but factory service manuals state otherwise.
