Back Seat Heater Vent
We had a passenger in the back seat -- they commented on "cold
air" coming from the center vent.
Sure enough it was cold.
We turned up the heat/temp dials all the way. Tried "feet" "feet,
center, defrost" and "auto" modes for both driver &passenger
settings.. Always cold air.
The only thing that seemed to affect it was the fan setting -- it did
blow more or less depending on the fan setting.
We rarely have passengers, so we never noticed it before.
I read that when the power goes out (change the battery) the heater
does a "self reset" kind of thing to reindex the stepper motors.
I did not know this when we put the new battery in - and I know I did
turn the car on & off rather quickly (just to verify the battery was
installed). So what I'm wondering is if this stepper motor is stuck in
one position or another -- or if there's something else to look for?
(dead stepper motor, connection/fuse) etc.
Thanks

It was fully warmed up & it was in auto -- cold air -- but I discovered warm air does come out thru the under the seats vent.. not strong, but warm air does make it to be rear seats -- just that center console vent always seems to blow cold air..Originally Posted by AllGo'n'Show

Why in the hell!!! I saw that photo before in my manual, but didn't believe it ... it's about 25 degrees F outside ... why would I want that pouring in
I thought something was wrong, just like jassing ... did a search and found this.
Thanks Shogun, but I can't believe this design ... why have it there at all.
Thanks again, now I know that I can't screw with it to stay warm.

Yea --- I agree.. but at least it's not something wrong...Why in the hell!!! I saw that photo before in my manual, but didn't believe it ... it's about 25 degrees F outside ... why would I want that pouring in

What I find worse is that when I shut the back vent to stop cold air from coming in -- it is forced into the car by the ebrake - where the two parts of the centre console come together.. BRR. I ended up opening the vent up to keep it from blowing right at me....

Yep ... I know ... it's freaking my body out because I have the seat heater on and yet my hip is being blasted cold. I also agree, I'm happy that something is not wrong, but I would almost rather go through changing something to have heat rather than ice.
Ken
hehe - Very true! I agree...
Maybe someone will be very inventive and figure an easy & 'stock look' way of pipping warmed air back there.
