Turn the knob for vents & ac but no air comes out?
The adjustment knob to increase/decrease air flow from vents, turn that but no air comes out of vents? checked the fuses under dash, but nothing seems to be blown there. A/C seems to turn on but can't get air to come out of vents.

There is 2 different radios. With or without rds. Here are the instructions for both.
Setting the Time for Radios with Radio Data Systems (RDS)
To set the hour, press the clock button. The clock symbol displays and the hour flashes. Turn the ADJ (adjust) knob to increase or to decrease the hours. To set the minutes, press the clock button again. The minutes. Turn the ADJ knob to increase or to decrease the minutes. The time can be set with the ignition on or off.
To synchronize the time with an FM station broadcasting Radio Data System (RDS) information, press and hold the clock button to enter the clock set mode, then press and hold the clock button for three seconds until UPDATED displays. If the time is not available from the station, NO UPDATE displays.
RDS time is broadcast once a minute. After tuning to an RDS broadcast station, it can take a few minutes for the time to update.
Setting the Time for Radios without Radio Data Systems (RDS)
To set the hour, press the clock button. The clock symbol displays and the hour flashes. Turn the ADJ (adjust) knob to increase or to decrease the hours. To set the minutes, press the clock button again. The minutes flash. Turn the ADJ knob to increase or to decrease the minutes. The time can be set with the ignition on or off.
When you adjust the positions for the vents, there are electronic solenoids under the dash that open and close the proper louvers to direct the air flow. There is a chance that that control has gone bad. As far as the A/C is concerned, I would check the condensor for damage, and have the A/C checked. The charge might be low.
what position is the control switch in? does this occur when accelerating?
the door that directs air flow is controled by a vacuum motor. the default position for the door directs air flow to the defrost vents in the event of vacuum loss to ensure the windsheild will be clear of mist. if there is a small leak, vacuum will temporarily be removed when accellerating and the motor will revert to the default position. there are vacuum lines from the control knob to the motor you must check these lines for leaks. the diaphram in the motor may be bad. also check the main vacuum supply line to the control knob. usually red in color. if there is a vacuum storage cannister. it may be leaking. this cannister will maintain vacuum for the circuit when accellerating. engine vacuum decreases when accellerating.
With the A/C off and engine running and up to normal temp check the temperature at the dash vents at medium fan speed.It should be close to the outside air temp.If it's higher you have hot air from the heater leaking in the air stream to the dash vents.Next check the A/C system for a full charge...NOT OVER FILLED or UNDER CHARGED. Next check for air flow through the exterior of the condenser. ( in front of the rad.)The fan should run when the A/C compressor runs.These are the basics. 90% can be repaired with these items at 100%.
Your message is a bit confusing but since there is a vehicle model shown, I'll assume that is the A/C causing problems.If the blower does not push air on either heating or A/C settings, the bearings of the motor may have gotten gummy and are not allowing the motor to spin up.
Check the different speed settings for the blower, preferably with the controls set to heating since there are additional controls when on A/C that can confuse troubleshooting.
If the highest speed is working, then the speed control resistor has failed.
If it does not move air regardless of setting, then the blower motor has failed or the bearings sticky.
If you have added gas to your home A/C, I hope you know which gas is used (R-22- NOT R-134 as in cars) and have not overcharged it since that can caused very high pressures that can damage your system.
Different systems also have different intake and output pressures with which the compressor and other system components work best.
sounds like your blend door is loosing vacum check for melted or disconnected vacum hoses (most are plastic) the blend door is controled by one black and one black w/green stripe. As for the e break check for connection or cracked or worn hose end
make sure the control knob on the dash is on "RR". This lets the driver control all the vents in the back. The heat only comes out of the floor vents, if you have the knob on the blue dots that represents the air conditioning in which the cool air will come out of the vents up above in the back. There is also an area on the control knob on the dash where you can turn the knob to shut the heat and air conditioning off. If the knob is in this position then you can control everything with the knob up above the seat right behind the driver's seat.
