Hi folks,

Two questions:

1) Today it's about 100F outside, and on a trip home from a nearby town (mixed interstate and hwy, avg speed 65 mph for about 25 miles), I was unable to get the temp. of air coming out of my center dash vent below 50F. Is that about right, considering the ambient temp. outside? Or, is it likely that I need to have the AC system checked for R134 charge levels, etc.?

2) If I do need to have the system checked, is there anything so exotic about the Saab AC system that a competent general service shop cannot do the job? (I.e., variable-capacity system and all that.)

best wishes,
David

Have you run the diagnostic test? Hold Auto & OFF and let it run it'll finish with the same settings you started.

Then take a measurements with the same settings on both sides.

Well, I'm kinda holding off on running a diag test right now. I know I have an 08 code and have a new aluminum blend door arm sitting on my desk right now. I just haven't scrounged up the dedication and energy to contort myself for the repair. I guess it's quite possible that the blend door is not fully shut and so some warm air is mixing with the cool. But I only want to run the test once I'm ready to do the gymnastics involved in the repair...

A Catch-22, I suppose: I can't really be sure of the state of the cooling without knowing the state of the blend door, but if I run a diagnostic test, the door arm may stick in a place that lets in a lot *more* warm air...
