Had the Mustang back at the shop today. I was told one of the spring clips on the end of one of the new hoses blew off. My mechanic had a Ford out in his yard that he took some pieces off to get it fixed. Recharged it and now it's blowing cold air again. This is for the first time since I have owned it, which is 2007.

yes the A/C kicks on with my a flex-a-lite 185 which works amazing and blows
3,300 CFM of air.

Should I buy this https://lmr.com/item/LRS-6888747/Mustang-A-C-Manifold-Service-Attachment-Charging-Port-79-93 as well or just a new pressure relief valve?

I got.the same fan for 18 years now and it works great. I did replace the motor on it about ten years ago.yes the A/C kicks on with my a flex-a-lite 185 which works amazing and blows

It regulates the flow of refrigerant in the system.
The orifice is what creates the system pressure drop that gives the AC it's ability to cool. You have hot high pressure upstream of the orifice. Passing through the orifice acts as a restrictor, so the pressure in the system drops immediately after flowing through. That pressure drop creates a cooling effect so your "low" side is now cold.
An orifice that is too open creates less pressure drop, and less of as cooling effect. Meanwhile one that is too small creates a restriction as your high side pressure builds up way too much and pops the pressure relief.
I would just replace what you need, unless the O-rings on the other manifold are not the new green units. Would have to track down the correct o-rings, or just buy a new manifold depending on cost.
As for the clutch switch, these are adjustable. There is a screw inside the connector to turn the pressure down fromR12's 25psi to around 20-21psi needed for R-134a
I believe it was summit racing,but its been a while.

Fitment Note
If the factory accumulator and compressor hose is utilized, this service port does not have the same half-moon shape inside. To correctly utilize this new service port, you must purchase a new A/C Accumulator & Compressor Hose.
would not having the proper acumulator cause
A/C Manifold Service Attachment w/ Charging Port to pop????
Attachments
No. That half-moon feature just allows the hose to rotate a little so when you tighten it down, it needs to be clocked in the right orientation.
The little half-moon feature just locked this feature in place. Without it you can spin it up or down slightly before you tighten the fitting up. Once tight it doesn't move
Should I just buy this kit and get it installed and charged up?No. That half-moon feature just allows the hose to rotate a little so when you tighten it down, it needs to be clocked in the right orientation.

Or just a new orifice line and accumulator line with new high side and low side pressure ports ? and a new Motorcraft clutch cycling switch? got to have my A/C working.
What happens if the evaporator core is not working? Is the accumulator drier area suposed to frost up and leak down onto the headers ? Or does that mean it's done too?
