Thanks for all of that info Bohica! Really helpful! One thing I still fail to understand is that if the fan clutch was the problem, why will I still not be able to achieve lower outlet temperatures when rolling down the highway? I can feel air being pulled from the front side of the condenser at idl...

Thanks once more Cusser... that confirms my fear, mainly because I didn't want to tear the dash apart to get to the evaporator plenum. I was concerned maybe the recirc door may not be closing/sealing fully, or the blend door for mixing the heat/AC might not be sealing fully. I have no typical noises...

I went ahead and opened all 4 doors and the rear hatch, set both the front and rear A/C to the coldest setting and the fans at the highest setting, and brought the engine up to around 2,000 RPM. The A/C...

So I hooked the manifold back up and was sure to not open the valves on the manifold itself-- just on the high and lower pressure adapter fittings. It was around 73 degrees ambient temperature and I was parked under a shelter, which wasn't even in direct sunlight, and I could only achieve around 50 ...

Thanks for the super-quick response Tim. I'll have to ask my buddy, he hooked them up while I was grabbing an extension cord for something, and I didn't check to see if they were opened or closed. My guess is open based. I'll hook the gauges back up this week, make sure they're closed, and report ba...

Hi everyone, I bought a well-maintained '05 Navigator last year, with around 110,000 miles on the odometer. Once summer came around, I noticed the A/C wasn't very cold. I put a thermometer in the dash vents and on the coldest setting, in recirculating mode, I was only getting around 49 or so degrees...
