The air conditioner is cold as ***** so that's fine.

Problem is just a couple of days ago my fan hasn't been blowing at full speed... unless I make a left turn (weird).

And only a left turn. Not when I turn the wheel left either. That does nothing. Only if I make a left turn driving the car, not sitting idle. After the turn it goes back to the slower speed.

My guess is something may be loose under the hood like an electrical connection or something and momentum from the left turn is kinda "forcing" whatever it is back into place for a quick second.

 

EDIT: All of a sudden went back to normal this morning. lol

 

Could it be that something got "moved" when you installed your stereo system, Gary? that the problem is actually in the dash?
Just cause it went away today does not mean it won't be back tomorrow.

 

the problem came back this afternoon.

im observing that the problem happens when it's hot out... when it's cooler it blows at full blast. and i thought about if i was just imagining that since it is hotter out and could give that possible effect and trick me... but no.

when it's hot, it does blow harder on left turns like mentioned.

when it's cooler, it blows just as hard no matter if im turning left or not.

and if it was something stereo related, I would guess this could have happened earlier than it did. the factory radio wasnt in that car very long. I'm at around 41.5k miles on the odometer. I installed the radio somewhere in the range of 2k or 3k to about 5k or 6k is my guess. Lots of miles in that time... and about a year time frame.

 

aye i figured out what it's doing, but dont know the fix...

the blower is fine.

it wont switch between vent and floor combo, and vent only. if i go to vent only, it stays at floor and vent combo. it'll go to all the other options, and go back to vent/floor, but wont go to vent only at all.

weird
