A/C values advice
My A/C is blowing warmer on the driver's side than the passenger' side. I have cleaned the duovalve and it looks pretty good. The resistance across the douvalve pins is around 25 on both sides. I don't have any codes it just reads FF when I do the diagnosis which I believe means there are no codes. Can anyone tells if there is anything out of line based on the following actual values:
sensor 1-75 inside temp
2-93 outside temp
3-62 left heater core temp
4-51 right heater core temp
5-123 evaporator temp
6-190 engine coolant temp
7-15 refrigerant pressure
8-255 refrigerant temp
Note:After testing the flaps I found that on value #2 (right diverter flap) the right center outlet did not respond even though this is the one that blows the most air when the A/C is on.

Bated breath
Moron.
He has his reply. He knows what to replace. And your WIS and lack of knowledge is apparent once again.
Baited breath? Even after two years and a name change and being lifetime banned from one forum,you still don't know the difference between Brake and Break. So how would anyone expect you would know that nobody waits with Baited breath but someone with a mouthful of worms.
Jack,you out do yourself daily, keep up the good work.
An Epiphany is realized, not bestowed.
I bestowed knowledge so he can actualize a remedy for his issue.

Evaporator temp sensor is being delivered Friday 6/1/12 will respond with the result after install. Hopefully this will resolve my A/C issues. The driver's side still blows warmer and the passenger side blows pretty cold. Once the sensor is installed the system should know how to perform. I will run the actual values after install and post.

I installed the new evaporator temp sensor from AutohausAZ p/n 210 830 07 72 this morning, warmed up the car for a little while, took a ride and extracted the following values:
1-71 inside temp
2-76 outside temp
3-42 left heater core temp
4-40 right heater core temp
5-49 evaporator temp
6-188 engine coolant temp
7-15 refrigerant pressure
8-255 refrigerant temp
Do I need to reset something? Do I have a different issue or did I just get a bad sensor? What do you guys suggest?

Here's the values after installing a new evaporator sensor and adding some freon.
1-80
2-84
3-35
4-35
5-40
6-190
7-15
8-255
Air is much cooler, but I am still researching what the 255 refrigerant temp is all about. I need to figure out which sensor reads this value.
Thanks for all of the advice.
