Does the blower spin or does the air not come out of vents if the blower does not spin it is bad if it spins but does not let the air come out it is the blend actuator under the dash
SOURCE: no air flow to dash vents and feet vents
99% of the time when they do that it is the control head. that is the thing you adjust all your temp settings on. have to purchase from dealer. have last eight digits of vin # when ordering.

the idea of the switch is run on vacuum and is not making contact with the switch it self either worn contacts in the switch itself **** as an obstruction as well or the vent door is stuck in just that position either behind the glove box or the ash tray are the vacuum lines one of them may be pinched off or the door needs a bit of help until you can free it up

Check the vac lines for leaks on the drivers side rear of the engine compartment. The ones going to the vac ball attached to the hood.

Sounds like it is going through the recalibration process. We run into this issue when replacing the batteries on these. In the underhood fuse block there is a HVAC fuse. Pull it, wait 30 seconds, put it back in, and turn the key to the run position. You should hear the vents moving around. wait for about a minute or so, do not touch anything. If the self test/calibration passes everything will return to normal. If after several attempts you can not get it to return to normal than there is a problem with the HVAC system that will need to be resolved.

There is a black vacuum hose in back of the glove box toward the top connected to a gray hose about 1/8 thick.You need to check to see if there is vacumm there.If yes then you need to take the bolts off to be able to tip the dash back enough to see all the vacuum hoses.Make sure they are all connected.It was alot of bolts but its is the best way.I had a hose off going to one of the acuator doors.Glued it back on and works great
It's most likely a vacuum line, look
under your hood (close to the cowl panel) for a disconnected, cracked
or broken vacuum line.
In some rear cases, it could be the
vacuum switch (in dash). Or vacuum diaphragm (under dash).
Hope this helps you ???
