Did you put a gauge on both the low & high sides? Those cheap gauges that come on cans from the autoparts stores will only tell you half the story. You need to put a gauge on both sides to know what's going on.

Also, just to prepare you for the foam issue. If you take it to the dealer for this, they will tell you they have to replace the airbox. There is no part to fix just the mixer. They will only do the entire airbox. MSRP is $2051 just for the part alone. Figure at least 6-8 hours of labor as well as a complete drain of coolant & AC as well as recharge of both. They will also most likely (they should anyway) include new o-rings and a new AC drier. Ultimately you would be looking at least $4k for the dealer to fix this....AND!!!! the foam will come through the vents again when it breaks down.

This is why there is a DIY on this. 2 method, through the radio or through the heater core. Half a day at home to do either and maybe $20 in materials.
