follow this line it the console, theres a box back therethe line runs to, then 2 yellow lines leave it to the vac pumps in the dash that change the air flow.

does all that work? the def, floor, vent. like you can change it still? if not id think that box is suspect for sure. or the line running to it.

car running listen for a hiss under there, or a cracked line. work the controls while listening. you'll hear air when its changing air flow, but it stops.
all that stuff is working fine except the blower in the car for the AC/heater quit a couple times since I've had the problem. I forgot to mention that.

I do believe it has the 180 Tstat in it. I can't remember because i put it in when i got the pcm and it still ran at 195. and it was leaking so i just took it out and put the stock one back in. but i think i changed it back around hoping i just didn't seal the coolant line properly or put the gasket on wrong or something. regardless, whether it was the stock 195 or the 180 the engine temp was still 195 or higher. it actually goes up to 210 usually during the spring and summer.
