In MY04 CS when I turn the heat on, it is throwing cold air on passenger side while the drivers side is working fine. I have tried changing temperature individually for both sides, but no cigar.
i read similar post here but it was more about air condutioner than the heater.
I had this problem about a year ago, but it started working again after a few hours.
Another issue is that there is no air coming out from front center ducts. This center duct problem somehow fixed itself for a short period of time in the summer when I was using A/C, but returned again.
Any suggestion what could be causing these?
This afternoon I was replacing the headlight switch/AC side vent and went to tighten the headlight switch into the housing and somehow struck something on the electrical board with the four wires and has the diodes and shorted something out. It smelled like a resistor went. Now I have no front fog lights and my AC appears to be out. I am not sure if the AC compressor is kicking on, though I have all the controls working. Any ideas what I may have screwed up.
Today I took the Cayenne 06 TT with 4 zone climate control to a shop to replace the damaged AC service valves and vacuum then regas the system to spec 1050-1100grams with 10g pag oil.
See image of new valves for low (right side)and high side (left side), as you can see they are vw parts and they pretty much fit any vw model and Porsche Cayenne and probably a whole load of other brands as the valves are generic for a lot of manufacturers and fit AC equipments which are standardise for obvious reasons. I went to Porsche and they didn't have any stock so went to vw and they had plenty.
Move the power steering reservoir out the way for easier access. Second picture.
The old low side valve (image 3) with manky looking chewed up Rubber valve which was stopping regassing according to the shop I tried 4 weeks ago after collecting from the garage who did the torque convertor seal job and left me with no AC working but before when I collected it (then had to return it due to massive vibration and a list of other crap), it did work which is strange but undercharged is all; (51oC when I collected it the second time with Jack all AC working thanks a bunch guys)!
So getting to the issue. . ......
Vacuum was fine no leaks, re-gassed to 1100 perfect, started car and ran AC, nothing but hot air. Gauge for high side was perfect in the green zone, but low side was much to high above the green zone and in the red. The technician concluded the compressor was good but the low side is blocked. He said the expansion valve is likely blocked and thus the low side is high.
So a few questions pls...
Q1. Is there any way a fault code or switch device/ sensor or valve located after the compressor could be off or shut and not allowing the refrigerant to not flow around to the condenser then onto the expansion valve and through the evaporator?
Q2. How to get the expansion valve out, any diy pls, I searched and found nothing.
Q3. Is there any other possibilities to consider?
Appreciate responders. Thanks
has anyone ever recharged their AC? I have a 2005 Cayenne Turbo. I noticed the other day the AC is not as cold as it used to be. Has anyone used AC Pro to recharge their AC? I believe the refrigerant is the same as what Porsche uses. Is this something that a novice can attempt, or will this damage the AC system by using an after market refrigerant that is not from Porsche?
I have water on the passenger (right) side floor board of my 2001 996 base coupe. Here are the signs and symptoms, and hopefully relevant info: the water seems to drip from the AC vent. The car hasn't been out in the rain or through a car wash since I dried it out thoroughly. Drove it for about an hour yesterday with the AC on, and the passenger side is soaked. When parked, a healthy amount of condensate came out by the left rear wheel (that's the driver's side, opposite the side where the floorboard is wet), bit nowhere else.
Based on the great info on this site, I checked all four drains under the front cowl. All four were unobstructed and dry as a bone, but there a couple of small leaves in two of them so I cleaned them out. My car has the little clear window over the VIN and the slotted drain grommets, so it looks like the TSB has been applied. I also removed the cover panel on inside of the passenger side rear wheel well. I couldn't positively ID a drain. The area was relatively clean - a little dusty, but no discernible mud, etc. Also very dry. I took out both rear speakers and felt around from the inside of the car all the way down to the bottom of the wheel wells. I suppose that tip only works on the cabriolet...it was clean and dry inside both and there was no drain line .
I ran the car with cowl under the hood/bonnet off and the AC on. The AC lines get cold and water condenses on them (both under the bonnet and running along underneath the car on the passenger side), but it doesn't leak or drip excessively. While it was running, I looked underneath, and saw water dripping from the plastic skid panels under the center of the car up forward. It didn't do that yesterday. I can't imagine that pulling out a couple of dry leaves from the drains under the bonnet made a difference...could it have?
I'm pretty sure that the issue is condensation from the AC system, since it's getting wet from no other source (and it's clear water, not coolant). It would help me to know: where is AC condensation water SUPPOSED to come out under the car when everything's working properly - front, rear, both? Is there a drain hose from the AC condenser that I can access somewhere up front other than as mentioned? I apologize if this is covered clearly somewhere else. I'm just kinda flummoxed...what am I missing?
Thanks very much for any guidance (even a link to some obvious other posting I should have found already)!
