  1. @Rick150 What are the wires running to the upper vent outlets? My center vent is needing of replacement as the previous owner had something installed and broke all the clips. Any advice?
  2. This is interesting, I'd like to know where this goes also, just in case I run into this issue at a later date..
  3. The hot air likely is coming from al the metal being heat soaked. The issue I'm having is my AC is charged, newer compressor, but the air never get ice cold... it'll get "cool" but humid. Drains are not blocked at all..
  4. I have a 2005 Turbo and I live close to Seattle, my mechanic at Gerber changes my oil with Motul 0W-40. I have the PDF for the oil list somewhere.
  5. Mine did it once (2005 Turbo) but only after I was in bed several hours. Narrowed it down to the rear glass was popped for some reason. Once I closed it up and made sure it was secure, I haven't had an issue since. Just something to check
  6. Will the Durametric tool be able to read those sensors? Sometimes I can feel it get ice cold for a few minutes, and then it levels off and gets kind of a cool "humid" breeze. There is a service record of the AC compresor being replaced about a year before I purchased it, but this blowing of humid air is terrible. I have checked the rubber drain hose that runs from the housing to the firewall, it's clear and open, and the hole in the housing is clear and open as well as the firewall dump.. Thoughts?
  7. Does anyone know where the interior temperature sensors are located? And why there is a wire harness running to some of the vents (like the center vent for example)? I'm attempting to troubleshoot an AC issue, and I've noticed when I open the windows and let a bunch of hot air in, I can feel the vents start to put out much colder air. Compressor was changed by the previous owner a couple of years ago, refrigerant level is also good.
  8. So, What do I need to check to get the headlight washers to work? I can hear the relay clicking, but I don't hear a pump sound and they don't pop out - I even checked the fuse, and all is good. Could it be a disconnected wire harness? Do I check behind the bumper? Or something attached to the washer reservoir that's behind the wheel well liner?
  9. Just curious if anyone had any input on the Radio Firmware issues? I also can't set the date on the nav unit, I can't even get to the option. I newly installed a MOST adapter so I can add Bluetooth/USB connectivity to the stock unit (loops into the fiber optics - hooked into the back of the head unit) Everything seems to function - audio wise - but I still get those triangle firmware issues. The GPS positioning shows correctly on the maps, but the "current location" in the settings menu shows Anacortes WA when that's 60+ miles away from me. Thoughts?
  10. Does anyone know what sensors and where they are located? I think mine may be faulty, because I can open the window when it's hot out with my hand in front of a vent and start to feel it get really cold. I roll the windows back up and then it goes back to blowing warm. It's fully charged and previous owner left service records indicating that a new compressor was fitted. 2005 Cayenne Turbo (9PA/955)
  11. I apologize. Just need some help with this rig. And for the software side of things also.. Like with the stereo. I have a handful of little things I gotta put back to normal, like removing the Parrot Bluetooth that was installed, it's junk. And trying to find the front passenger footwell light wire harness, because I took out the glove box and kick panel and it's nowhere to be found.
  12. I know this is an old thread, but I need to know where you got those hose clamps for the vacuum lines? The ones that look like factory?
  13. So, mine don't make any noise at all. No honking/screeching sounds. On occasion, I can hear them bleed off excess pressure, sounds more like a "woosh" and isn't very loud. I think I'll order the N75 valve, and also pick up an air compressor (as I gave my old one away a long time ago) to see if I can pressurize the lines to see if I can get the waste gates to operate. I did pull the MAP sensor on top of the Y pipe of the intake. There was oil residue, and I looked down inside with a flashlight and it just looked like a very light coating, and probably nothing to worry about.. Would a Dirverter Valve failure also cause an over-boost condition? Also, is the valve up front the N75 or the N249? Looking around at parts, they seem identical. - EDIT: Never mind, looked around a bunch more and it seems to be part of the EGR system.
  14. Found a guy that did his own diverter valve replacement, I was already considering this "upgrade" as a PM. Are the lines running to the DV valves what I should be checking? Or should I be looking at sensors or the threeway valve that's on top?
