Okay, so I know I have seen this issue around the forums before but I can't seem to find it.
The air set on max will not blow through vents, only through the defrost. It worked fine before I began performing a radiator flush/thermostat replacement.... in which I discovered a pretty sweet leak from the thermostat housing..
When changing the T-housing I did the following (I like the room when working):
I disabled battery
took the intake off
took serpentine belt off (replaced it new)
alternator off
various hoses and electrical connectors (replaced upper/lower rad hoses, small upper and the lower thermostat housing hoses)
Installed the new housing and put everything back together.
Gently put in the sensors and then I cracked one of the sensors (accidentally over-tightened)
So then I did it all over again with a new housing and new sensors...
Everything put back together and resumed my radiator flush, car starts and runs fine, check for leaks... notice there is a real tiny leak from top of one of the lower housing bolts. Shut it down and try to gently snug it up and the dang bolt broke. So, dealing with that.. (It's been a friggin journey...)
Anyway, in the meantime, while the car was running I noticed I had this issue with the air and I'm assuming it's something to do with a vacuum hose I must have bumped or broken.. but I'm not positive. Anyone know where the basic starting point for this problem is?
I just changed my blend door actuator before doing this so I was excited about hot air again... ughhh.
Thanks
