This is the biggest reason I think 95+ were better years.

Have you tried lowering the desired temperature set point a little? The ECC should transition to send some heated air out the dash vents. Or do you want maximum heat from the dash outlets? The ECC in these GM cars can be a tad flukey at times.

I had it set on 27 degrees Celsuis...nearly 80F. The Aurora has an ECC, however its a little more user friendly, I can control the direction of the air thru the vents in any or in a combination of directions.

Oh well...as long as its warm in the Bonneville somehow this winter.

remote starter!!!

My car still has old dial controls So at least does what ever. I tell it This could out of post did better trim levels have option auto lights my car looks like it has spot for sensor

Sometimes I wish I had manual controls for the ventilation modes, fan speeds etc. There are fewer problems with those systems & easier operation.
