You read my mind, we did the evac and weighed the refrigerant back in and then took a hose pipe and run water over the

condensors and vo'la!!! got it. The high temp and maybe it was a little overcharged,and maybe the need for the hose pipe to be run on it, so whichever it was all cleared up and we now have cool air!!!

Thanks,

Yes what I have is the low side is about in the correct range 70-ish and at first the high side seems ok but here in Alabama right now temps are in the high 90's so I have some fans blowing on the condensers to try and portray going down the road at a moderate speed but he high side is going off the chart over 400 so I cut the

air off cause I know that is way to high.  So just trying to figure out if the expansion valve is not working properly.  That what the old rule is if the low side is fine and the high side is high there is a blockage of the orifice or in the cars case maybe an issue with the expansion valve.

Thanks,

Hey Ahsai  thanks, got most of those documents already on file.  I also found a great deal of info

just tooling around different forums most say its built in on these particular valves so its not visible

outside.  But thanks anyway!!

John

Not an AC expert and for some reason since I have gotten the system charged up the low side seems perfect  but the high side

just keeps climbing?  I looked at the expansion valve and don't see anything like a normal capillary tube type where the temp is

monitored by it and opens and closes the expansion valve?  All I see is a little disk looking thing on one end of it where it attaches

to the evaporator.  So I am wondering if it may be not opening does anyone know how it should work?  This is a 1999 c2 and just

wondering what actuates it if anyone knows please.

Thanks in advance,

John

Thanks guys that helps alot, I'll dig a little deeper now that I know is suppose to be a variable displacement compressor

Thanks again,

John

Does anybody know how the compressor runs normally in a C2 996 I'm having some issues and I'm

not sure if it is suppose to run all the time or if it short cycles and if it cycles what determines the time

run and time off ?  Weather here in Alabama as of late has been a little warm and its a shame to let

such a great car set in the garage because the air isn't working!

Thanks,

John

My 996 is having a issue with the AC relay.  I have tested everything and have found I have all

the things I need except the 85 pin which is the ground signal from the DME.  Does anyone out

there know what permissives the DME is looking for so I can check each and see which is missing

please?

Thanks,

John
