i gave auto a chance..an honest chance... i used it 2 days exclusively. but no heat ever came out the top vents to warm my hands and face so i guess my actuator really is fried..sigh

i had to manually press the bilevel button to get it to work

i also find it hard to take off auto. just pressing auto doesnt work, the auto light and recycle thing on the dash lights stays on until you really play around with things.

also i dont think auto really works well from the little i used it. for instance if you are happy with the temp set at 75, it takes longer to get there vs you cranking the thing to 85 for a bit until the car fully warms up. i'm assuming the air coming out is hotter at 85 than 75? i still dont fully understand the system i think.

I always like using it in auto. The wife mainly drives the car and when I get in to drive it is usually switched off of auto so I guess she doesn't like it either.
I just press auto and ours turns off of auto.
I am not sure how it decides which vents to use when cooling or heating in auto. I do notice in heating it doesn't seem to blow out the vents pointed at your face I guess because it is trying to get an overall warmth in the car and blowing at you would make it seem too warm? Not sure. when cooling it does however come out of the vents at my face.

i knew i had a thread on this. i guess ill just enter more observational data. the AC is def not broken but this is annoying

we are in the heat of summer now and i started the car on lo and after 45 min i still was not 'freezing' but definitely tolerable. i crank up the temp to 65 (cause we all know increasing temp makes it cooler) and its so cold i cannot stand it lol.

maybe its just always opposite day with my car

not enough to really even think about attempting to fix.

and in the morning when i get to work the car is already on vent lo but i switch to AC lo before turning off the car so it can be precooled.

maybe a relearn on the blend door is needed? or a new temp controller (i've seen those for about 20 bucks on ebay previously.

so i have a cheap solution guaranteed to work on everyones car.

we've only gotten up to about 80 ish here so it is not a 100% proof test but id say its 95% a solution.

after 174K i finally changed the cabin filter. i highly recommend more frequent changes.

the volume of air has measurably increased. i know the car didnt get as hot as a 90 or 100 degree now. but ive reached tolerable good temps within 5 minutes of driving. vs having to wait over 30 min before. if this continues once we get 90 degree days then its the solution. also after about 10 min or so i gotta turn it up to 70 so i dont freeze on LO.

i dont even precool the car anymore. last summer i used to do it 20 min before i went out to try to take the sting out of it
