What is causing the air to be so hot when the setting is on vent. How to make it operate correctly??? It has been like that since new.

 

Mine does this too, I think it's because I have a leak in my vacuum system (vents/4x4).

 

Anyone else had or fixed this issue?

 

I'm curious as to why you didn't take it back under warranty????

I too would think a vacuum leak.

 

Does the AC work properly?

 

Yes AC works great. Say it's 60 deg out, on vent it will be warm. I never took it in because in Phoenix I rarely would use it in vent.

 

Mine always starts out warm but in a minute will cool down to outside temps.

 

I havnt had that problem but I did notice that the ac is cold or hot. Ex. I had it set at 60 the coldest it goes, then i tried going to 72 and it got warm...not cool but warm.WTF? I want a happy medium but no no, you freeze or sweat.

 

heater control valve failure maybe?

 

That valve is only closed at the Max A/C setting.

 

the mixing door is vacuum actuated, right? That's about all I can think of that could cause this? You're getting hot air all the time, and it takes full cold to make it 'balance out' to cool.

 

Didnt want to highjack agemechanics post or anything. Sorry AgeM.

I just thought maybe someone might have same thing as I do.

Thanks
