I have a 2000 Ford Excursion - 7.3 Diesel. A/C not cooling in low RPM but system has freon

SOURCE: Warm air from dash vents but cool air from defrost

The system just needs to get all the air pockets out if you switched everything like you said look around where the radiator hose meets where you put the thermostat in, there should be something on the lines of a little nipple with a 8 mm bolt on it i will have to pull up the exact setup of your Taurus but its the same general concept your car is fine you just have a big air pocket , what else you can do is while its cold right now and the car isnt running is to go take the radiator cap off the radiator and see if the antifreeze is low now that the car has cold down since you last ran it. If so feel it up top it off in the radiator and it might hurp it self and remove the air pocket all on its own... If you need any more help feel free im always on here id be glad to help more in detail once you try that and look under the hood for the bleeder ( the thing with the nipple on it) Also if you could please rate me i would greatly appreciate it.

Thanks,
Steve

Networking Configuration A network architecture is a set of standards for how computers are physically connected and how signals are passed between hosts. Some typical network architectures are described in the table below.
Network Architecture Description Ethernet Ethernet is a wired networking standard and is the most common networking architecture used in LANs (both in business and home networks). Dial-up Modem Dial-up networking is a common way to connect a computer (often your home computer) to a remote network, such as the Internet or a business network. A modem on each computer uses the phone lines to send and receive data. DSL (Digital Subscriber Line) DSL is a fast-growing alternative to dial-up networking to connect to the Internet. DSL uses regular phone lines to send digital broadband signals. ISDN (Integrated Services Digital Network) ISDN is another alternative to traditional dial-up that can be used to connect to the Internet or to directly communicate with another computer connected to the ISDN network. ISDN is more common in Europe than in the U.S. ISDN can use regular telephone wiring, but must be connected to a special ISDN network. Wireless Wireless networking uses radio waves or infrared light (with the air as the transmission medium) to send data between hosts. Wireless networks are common in homes, businesses, airports, and hotels. Most wireless networks connect into larger wired networks (such as LANs) which are in turn connected to the Internet. Communication between hosts on a network generally takes one of three forms:

• Simplex--one-way communication from a sender to a receiver.
• Half-duplex--two-way communication between two hosts. Communication only travels in one direction at a time.
• Duplex--two-way communication between hosts. Communication can travel in both directions simultaneously.

The performance of the heater indicates low coolant level. Pretty strange about the multiple water pumps, but if is is under warranty, you need to keep going back to the dealer. They must be missing something...
