I replaced the AC compressor in the 2008 Expedition over a year ago and everything went well and is still looking good and very cold.
I have a 2004 Thunderbird that the AC hasn't worked for a very long time ago. I started with the clutch fuse and found it blown and replaced it. I then hooked up the pressure gauges and found no pressure. I hooked the ac vacuum pump to it for about 2 hours total high and low side. Is it odd that both the high and the low side seemed to have separate vacuums? With me being unsure of the total oil remaining in the system, I let the system suck in 3 ounces of PAG 46. It calls for 7 ounces. I then put in 3 ounces of the 134 A with stop leak and then started on the first 12 ounce can of 134 A. It is over 90 F now. After it wasn't taking any more, I turned on the car and the AC. I didn't get the full can in yet and the system calls for a total of 28 ounces. So I am about half of that. The high side I think is getting to 160 PSI and the low 90. After some time it was a bit more even like 130 PSI. I took off all of the gauges and the low port is next to the compressor and is very very hot. I could barely take off the hose because of it.
Does this sound like the compressor? Do these symptoms point to anything else like the expansion valve?
