@bandit In theory you can diagnose a system by hand. Touch the discharge line, it ought to be about 140 degrees. If it is 200 degrees, you have high head pressure and a plugged or over filled condenser. Though it won't stay hot long because it should cycle on the high pressure switch,
If it is hardly over ambient, its not pumping or there is no flow due to low charge. Though low charge should be cycling the compressor on the low pressure switch.
Down stream of the expansion device should be maybe 25 f. If it is a big ice ball, you have a plugged expansion device.
If the suction line should ba about 40 f. If it is 25 f. you have a plugged coil. with no airflow.
By the way, could it be possible that your blend door is stuck on heat? Is the air unusually hot when you are in AC mode and you shut the compressor off?
@cb Haha, to be honest, it's largely an issue of space. We live in a city, and parking is limited. As it is now, the C5 and her 1-series occupy the driveway, and the Jaguar gets parked in the street.
Here's a CIA Google Maps view of our house. The red is our property line, the yellow is our current fence line, and the blue is the current walk-through gate.
Our long-term goal is to redo our fencing and replace the walk-through gate with one wide enough for cars (preferably motorized, because I'm fancy). As you can see, we have a pretty sizeable detached garage behind the house. Definitely enough room for two cars. Could probably squeeze three in there if I moved all my brewing equipment out, which I'm not going to do.
I think the conversation would go much more smoothly if we did all that first. Then, I could fit the C5 and maybe a project car in the garage, and we'd still have the whole driveway to utilize. I'd likely keep the Jaguar street-parked though, as it has always proven to be a hassle juggling cars in the single-file driveway.
My former BIL bought a new Starlet just like this, just before my sister married him. A month after their nuptials, he ran into the back of another vehicle and totaled the car. The impact was hard enough to force the driveshaft through the floor. This was surprising to me, because I had always thought that they were FWD.
