I feel air coming from the circle area. The AC Blows Cold, and the pressure on the low side is in range. What am I looking at here? This seems to occur when I turn the blower/AC on.

 

Those are your a/c lines and probably not leaking if your pressures are good. Those are going into the blower box and are attached to the A/C evaporator. what is probably happening is you're feeling the air movement from the blower motor. Probably have a bad seal inside the box

 

Dash has to come out eh?

 

Maybe get someone with a thermal camera to look before you throw the parts dragon at this. (Especially if you don't have an acute problem.)

I recall always "feeling" air movement in this area, but have always chalked it up to convection. Those connections you circled are very cold and if you are in a warm/humid place, the air around it will cool, descend and all the other air around it will move.

 

Hmm, it just seems like vacuum/air coming out or spreading in that area.

 

I personally wouldn't give it a second thought unless cooling and heating was being affected. Especially knowing the dash and the intake have to come off to do anything with that heater box

 

The air you feel blowing at top of the cowl is actually sucking into the HVAC system. When it is not set to recirculate it pulls outside air threw the cowl into the blower motor and then blows into the air box and across the evaporator.

Feeling cold air blowing out by the suction line under the hood is normal as these cars age. They have foam seals at the evap case to keep as much air as possible inside the case. As these cars age they harden or fall apart all together and the air leaks start.

Bout all you can do for the air leak by the lines is get some evaporator black asphalt tar tape dum dum from oreillys and mold it into the area around the lines. IF you ask them at counter you'll get deer in the headlights looks. Tell them to go look at their HVAC book and its in the back. It's in a 2" wide roll.

 

I'll be this is it.

 

Yeah, this seems accurate, does anyone have a picture of where the foam should be? Is it in the area right where lines come through the firewall?
