Saturn Posted February 28, 2017 Share Posted February 28, 2017 (edited) So after a recent off-road bout my upper a.c. vents i, the cabin won't blow. When I run the AC on I can hear the fan and everything start moving, and the vents in the footwells work perfectly but nothing comes out of the vents in the dash. I pulled the glove box out and the cabin filters were dirtt, I'll change them, but I started the system without the filters and still nothing from the vents, even when I sealed the slot for the filters. This is really frustrating, the AC system obviously works, it just won't blow out of some of the vents. 2002 LE by the way, electronic HVAC controls. I've looked around and no one else seems to have this problem. Any ideas? Edited February 28, 2017 by Saturn Link to comment Share on other sites More sharing options...
RIPB.88 Posted February 28, 2017 Share Posted February 28, 2017 Sounds like the little flapper door that opens and closes when you select vents isn't working. Never torn apart an R50 before, so I'm not sure exactly where its located. Link to comment Share on other sites More sharing options...

With that you will be able to test everything on it from led to mode and intake door motor as the input signals too. I suspect the mode motor which is under the steering wheel, on the right (directly on the left underside of the center dash).. With the fsm, you will also be able with an voltmeter, to test if the motor is still good or if it is a piece of something that is stuck in there... s. 1 Link to comment Share on other sites More sharing options...
whatchugot12 Posted March 3, 2017 Share Posted March 3, 2017 Anybody know where to get the "blend door cable"? For a manual controled heat and air control panel????? Sent from my SAMSUNG-SM-G900A using Tapatalk Link to comment Share on other sites More sharing options...
Saturn Posted March 13, 2017 Author Share Posted March 13, 2017 Problem found, my blend door actuator went out on me. None of the parts stores near me have it so its gonna be a dealership or junkyard trip, in the meantime i managed to get the blend door all the open with a screwdriver, so the AC blows hot all the time, but at least I can just roll down the windows when it gets hot. Thanks for the info everyone! Link to comment Share on other sites More sharing options...
