Hi all. Was driving my 2003 996 cab 2 days ago. I heard a strange noise from the rear and pulled over. I smelled a burning type odor and a small amount of white smoke was coming from the trunk vents. Since that time the a/c is not producing cold air. Fan still produces plenty of air, but it isn't cold. Am I looking at a blown compressor here, or are there other possibilities? It gets rather warm in South Carolina, and sometimes rather than dropping the top I use the a/c. Any input from any of you would be greatly appreciated.
Thank you in advance,
My A/C has been getting warmer over the last week to the point of just warm air. The compressor is engaging as I can see, hear, and watch the tach drop slightly as it does. I figured it just needed a quick recharge, but the low side pressure is ridiculously high at 90psi. Before I go and pull the world apart does anyone have experience with this scenario? Does this point to a bad compressor or Refrigerant Control Valve? I'm not really finding anything in the search dialog.
I have a vacuum and used it on other cars, but have never seen this "overcharge" high pressure issue. I guess I'll try to lower the pressure first, but I have my doubts it will fix anything.
Thanks in advance for any input.
Hi - on my 06 CTTS, over the last few months I noticed occasionally awful smell inside the cabin while driving. My research so far indicates that it is emitted from vents when AC system is on. Believe it smells like sth. burned, and is not present when I switch AC system completely off. Did anybody experience this before on a 955 Cayenne, Turbo or Turbo S ? Thanks in advance.
PS.: side note. It may be coincidence or completely unrelated, but as far as electrical problems I am noticing for about comparable amount of time that the horn is dead (silence when pressing the steering wheel center...).
Let me start by saying I'm not a mechanic, so I do not know the names of certain parts. This is of a 2004 Porsche Cayenne Turbo w/ 4-Zone Climate
However, what I do know is, the A/C electric motor (955.624.915.01) under passenger side dash is steadily going back and forth regardless of A/C or Heat On/Off, High Low, Dash,Floor, Etc. It connects to a flap on the passenger side firewall. Pictures are of the same part, just different angles.
My question is this. How do I test this electric motor to determine if it is bad? Or could something else be bad causing the motor to constantly move? Any response will be appreciated.
OK, I can't be the only DIY guy to make this mistake (fingers crossed)... I had just completed bleeding the brakes and clutch up on jack stands (in last minute prep for my DE the next day) and was jacking up the rear to remove the rear jack stand and the car is so stiff it came off the front and rear jack stands simultaneously (normal). I then removed the rear stand and began to lower it back down and the front passenger side jack slipped off the lift point and crushed the outer AC hard line almost completely. I instantly thought it was the cooling lines and I layed on the ground in defeat for about 10 minutes knowing I had just threw away my weekend. As I lay there staring at the ceiling on the concrete floor, I then realized it was not my cooling line (too small diameter for cooling), it was my AC line and I was back in business!
The line was not cracked through, but as you can see in the pics the inner diameter of the line is probably reduce by 80%... so I resolved to just not run the AC until I fixed it later. Of course it was all day rain and the cab was so foggy to see, so I had to run with AC on all day anyway... and it ran fine!
My question is this... Option A - if it runs OK and is not cracked, can I just let it go and no further harm will come (besides my pride)? Or Option B - I am compromising the life of more expensive parts of the system ($1300 compressor due to reduced oil flow, etc) if I don't get it fixed asap? If the concensus/ recommendation is to fix it, what parts besides the hard line (and two new seals) do I need replace (e.g. Dryer/Desicant module, etc.)?
Thanks for the quick reply... I only have 2 weeks before my next DE and I gotta decide quick! Be gentle...
P.S. - the line is cold to the touch when AC is on... is that normal or a symptom of this crimped line?
