When I worked at Haldeman Ford, I got all the diesel and electrical work. I was happy to shovel the bullshit A/C work to the certified tech. :gtfo: Unfortunately, it's my wife's car, so I can't get out of this one.
When we first test drove the car at the dealership, the A/C blew warm. Like 75 degrees warm. He said it "just needed a charge." I rolled my eyes at the standard excuse, knowing full well there was probably a gaping hole in the bottom of the compressor or something. When we went to pick it up for delivery a week later, he said he had it charged and it was ice cold. That lasted less than two days.
Assuming small leak, I stopped by my work and picked up the generic R134a refillers and thought about the stop leak one. Thankfully, I didn't buy that one. I put the gauge on and it was in the super high "danger" zone. Remembering that an overcharged system functions just as poorly as an undercharged one, I responsibly evacuated the system with an environmentally-safe A/C machine. I recharged the system to the blue "filled" portion of the gauge with the A/C system on Max Cool just like the bottle said. I filled it to the middle of the blue zone. The compressor clutch was not engaging, and I went into the cabin and it was still red hot. After a few minutes, the gauge was reading the top of the blue zone, then higher, and finally back in the red.
So I stopped being a vagina and I got my first real professional set of gauges. The compressor clutch still does not turn on. My readings are 46 psi low side, 48psi high side with the A/C in the off position and 46 psi low side, 49 psi high side in the A/C Max Cool position with the blendoor turned to full cold.
I ran the OASIS on my VIN for
1) Climate Control (208000)
2) Lack of Cooling AC (208200)
3) Other Climate Control Concerns (208999)
It turned up no applicable TSBs or SSMs.
On to the online service manual...A/C symptom chart...Insufficient A/C cooling...go to refrigerant system tests.
It is about 85 degrees outside and high humidity, so picking the right chart, my pressures should be...25-45 low side, 140-250 high side
clutch cycle times should be 60-infinite seconds on, 3-12 seconds off
taking that information to the charts...normal low pressure, low high pressure, no cycle
none of the categories fit those conditions, all the normal low/low high have fast or erratic for cycling
so I am stuck with:
Erratic Operation or A/C Compressor Not Running
possible problems:
A/C Cycling Switchâ€â€Dirty Contacts or Sticking Open
Poor Connection at A/C Clutch Connector or A/C Cycling Switch Connector
A/C Electrical Circuit Erratic
There is no pinpoint test linked, and I cannot find one for the A/C cycling switch. :help2:
