A/C Auto is going to defrost

I have a 2014 Grand Cherokee Laredo. When I turn the AC to auto, it goes into defrost vents. When I switch back to AC it stays in the defrost vents until i change it to the face vents. Is this something of a user error or computer error?

Re: A/C Auto is going to defrost

This may be by design, mine does the same thing. When I first get in the air comes out of the defrost vents until the air either cools or heats up then it switch's automatically to the front vents. My guess is you don't want hot air in the summer blowing in your face or cold air in the winter. Once it reaches operating temp it should switch to the front vents as mine do.

Re: A/C Auto is going to defrost

I haven't used the A/C in mine since I bought it (still in the 60s here...) but it does the exact same thing with heat.

Of course the defroster heats up extremely quickly and STAYS on max speed until the engine is warm enough to put hot air through the front vents. Its actually pretty annoying since it just drys out my eyes, but it seems normal. 99% I don't use auto climate, but we'll see once I try the A/C
