Dash Air Conditioning recharge

Hello.

Before I  started looking,  can someone help me out with locating the ports to charge the Dash A/C. 

Are the ports in the engine compartment or the generator area?  Any advice or suggestions would be greatly appreciated.

I had my dash A/C recharged last season after my compressor seized and shredded the serpentine belt. All of the recharge fittings are below the windshield in the generator bay on my 2007 Beaver Contessa. Easily accessible.

I recharged mine 05 sig Detroit diesel and the port is in the rear right by the serpentine belt.

Mine are on the A/C compressor in the engine compartment.

I also have a 2004 model Monaco.  We have A/C ports both up front and in the rear engine compartment.  You can spot them by the red and blue plastic caps over the Schrader valves.   I used the vacuum pump on the port up front for about 30 min and then moved it to the rear engine compartment ports for another 30 min.  Then recharged from the rear port. 

Also, the dryer is up front just to the left of the generator and the system takes 4lbs of R134a.

Does anyone happen to know where the expansion valve is located on a 2003 signature?

I just replaced our expansion valve last week.  It is up front above the generator.  It has two black AC hoses connected with some black A/C insulation foam over the B nuts. 

I first removed the hoses.  Then peeled back the insulation and broke the nuts loose and it came right off.  

I had to buy some new green orings when i reinstalled the new one.  

Part number: EGELHOF AC Expansion Valve 1268300384 / 0751.0003A 321300S

Vito,
I ordered and received the part but it is different from what you installed.
The part number is the same but it is missing the attached probe at the end.
I assume that is some kind of a temperature probe but I wanted to check with you.
Please see my pictures attached.
Thank you for your help.

Hi Lee,

Yes, I'm guessing that's a capillary tube for temperature.  They probably deleted it for cost saving.

Your choices are to try reordering, keep the original part, or install the new one.  I think I'd try the new one.   

Good luck!

Good advice. I ordered a new one. The original came from eBay caridautoparts and the new one, including green O-rings at .99 each, is from autohausaz. The caridautoparts eBay dealer was not even remotely interested in any kind of a timely resolution so I filed for a refund.
Thanks again,
Lee
