Hi James, by the way I live in Sahuarita near Green Valley.......

Yes it is fixed, I now have air blowing from all registers and not just from the defrost and floor.

this is a quote from me on what I found......

One or the other of my explanations solved it.

1: I fixed the vacuum leak at the faulty canister by bypassing it.

2: I was reading the manual looking for any bit of information and I came across the non climate control A/C controls and it stated that when the A/C is on DO NOT SELECT THE DASH VENTS, if selected it will turn the A/C compressor off and flow outside air in the car.... I thought that was strange....... I have climate control, can this be the same for it.... I read the climate control part of the manual and it never mentions to select the dash mounts and to select the AUTO mode, when selecting the auto mode the system automatically starts with the defroster and floor vents then after a short period of time it automatically selects the best way to cool the car down. Well I decided to try that technique and guess what, I have total air now.

I feel happy about it, just don't know what the fix was, me or the manual.....

I forgot to ad one more thing that you just reminded me, I can select the dash vents and air will come out from them, infact it is blowing out at a good force so I guess the correct fix was bypassing the leaky vacuum cannister and not the manual.

thanks for all your help and information on where to look for the problem points and pictures you uploaded.

That still doesn't explain why when the display showed that the air should be coming out of the dash vents it was actually coming out of the defrost vents.

COngrats on fixing the problem and thanks for detailing your troubleshooting steps as this could be very helpfull for other members

The vacuum line going into the firewall is passenger side right next to the main wiring harness going through the firewall. Might be purple.
