Question about 1999 Acura TL

1 Answer

I have added the gas in my A/C at home but no air flow from vent

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. Thinking that I might run out of the gas in my single family house A/C so I have added the gas but still situation is remain the same and there is no or a very very little air flow from the vent. I wonder why?

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.

I have a 2002 GMC Envoy XL that blows cold air from the rear heat vents. What could the cause be?


the heat accuator could be bad. It is a motorized part that adjusts your temprature by allowing cold or warm air flow when you adjust the temprature at the knob you are turning

The AC air comes out defrost sometimes and comes


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.

Turn the knob for vents & ac but no air comes out?


Check to see if the plastic knob has been stripped. Pull off the plastic knob and see if just turning the metal underneath makes a difference.

The Air flows through only the defrost and feet vents


Inside the ventilation system there is gates that open and close to direct the air flow. These are operated on vacuum on most vehicles. The hose for that perticular gate may have disconnected somehow or has a hole in it. I suggest you take the heater controls out and see if there is a plug with a series of colored hoses on it. it so you'll have to trace each of them to see which one is the problem. Now you may be able to get some help from you local dealers mechanic who just may know the color code for that gate. (which would be a bonus) Good Luck

No air flow through the rear vents with ac or heat on high


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.
