Right...the only opportunity I have had to try small tests is while at work..

I didn't have spare leads around to apply 12v to the connector.. I did however test the ohm.. Getting 12.2ohm.

When I disconnected the valve it did not seem to change pressures..which make me feel it is seized from ...

Hey guys.. I wanted to follow up some more for future searchers with the same issue..

Always seems like people find their answer but never post the end result or solution.. So frustrating..

I found this searching for RCV failure.

This guy did exactly what I had planned to attempt to see if it ...

I just ran across this.

Ah thank you for replying.

Do you happen to know a way I could test the refrigerant control VALVE (RCV) ?

I suspect this is the issue due to the odd pressures I'm finding.

Or possibly do you know the symptoms of a bad RCV? This a common failure? I know many just get instructed to replace the ...

Hey.. I had some miscommunication.

I find out.. It's a 2008 xc90 6cylider.

Maybe I am using the wrong terminology? But this control valve

This is the item I am talking about.. I did see this on his compressor..

I used my multimeter and got 12.2 ohm. With it disconnected (testing valve itself.. I don't know the proper range for this though)

Stupidly.. I ...

I appreciate the reply.

But I don't think the temp sensor would have much to do with the pressure readings I'm seeing.

From what I gathered.. If compressor is running/engaged.. And the pressure is equal on both sides.. That usually would mean the compressor is bad.. However.. This isn't that way ...

Hey guys.

Working on a friend's 2005 xc90

Symptom :ac not cold except occasionally when fan was on low speed setting.

-compressor is engaging.
-Suction pipe is semi cold(not sweating .. Discharge is warm)

I hooked up my manifold gauges.. Strange I got suction (low side ...
