I picked up another 09 P71 a few weeks back. Everything works and it runs fine but I have a few issues. The cel is on but my scanner won’t connect to it. I was told it was the fuel rail pressure sensor, it doesn’t affect driveability so I’m not too concerned but I’d still like to read codes.
The fuel pump will run continuously while the key is in the run position with the car off. If I was a betting man I’d say the two are related.
When I let it sit for a few days, when I turn the ac on there’s a loud almost like the sound when the blend door actuator breaks but is more metallic and loud. I’m guessing it’s the ac compressor not wanting to turn. Once it started smoking before I turned it off. Once the compressor turns on there are no issues, it’s only after it’s been sitting. Could it be an air gap issue or is the compressor going south?
Also the wipers and fluid pump don’t work. Since neither function works and all the fuses are in tact my guess is the multifunction switch. Any way to test it?
