Does the Monty Sport 3.5 V6 have a capillary system on the A/C? and what could cause the supply to have unusually High pressure and the return to have Low pressure? I think there is an issue near the coil in the firewall, a clogged screen or is there something else? I have addressed an issue with a Schraeder (sp.) valve leak and the bubbles that were in the freon cleared up, as viewed through the viewing glass in the resevoir. Im a DIY guy and hope anyone with answers can give me some hints.
I live in Phoenix and there is no way to handle 110 degrees without good a/c - HELP!

 

I think its the "expansion valve"
does anyone know where it is located?

 

Mike,

I know a good sized group of mitsu 4x4 owners in the Phoenix area. If you want, send me your contact details and I can put them in contact with you so that they can possibly help.

 

Spoke with some of the guys there (I'm in Cali)

They suggested you check for a plugged expansion port/orifice tube/expansion valve which is sometimes caused by the compressor coming apart. []

Can you post your pressure readings?

 

I will check the gauges again, I was told a broken or totally clogged expansion will yeild a reading of ZERO- common sense stuff... It may be clogged so I thought Id ask before I go tearing into the vehicle. Thanks man!
If I recall the readings were around 30&180
I'll have to discharge the system and hope the expansion valve isnt a beeatch to remove

 

the expansion valve is in the suit case behind the glove box i just did mine autozona on line sell the valve for $43.00
