Hi guys,
i am a proud owner of a 2010 Porsche Cayenne base, and I love this vehicle, but I’m having a issue with the AC blower motor, when I first turn on the AC and put the fan on high it blows but not very hard then all of the sudden it jumps to high and runs perfectly, does anyone know what could be causing this, I’m hoping it’s just the blower motor resistor. Any input would help.
thanks in advance
sincerely
Paul

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.
Makes sense.
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?
