Air conditioner appears to be stop up on the driver's side. Changed air conditioner filter on the right side under the dash board; helped some. are there any more filter under the dash?

Locate the blower motor resistor and remove it. See if you can moves the leaves that way. If not, you may have to remove the blower fan

Looks like you checked all the things that need to be checked except "one." Sounds stupid, but did you check your temp switch on you dash to make sure it is the air conditioner you want to run instead of the heater? Sometimes, many forget this one simple check and can't figure out why the air conditioner won't engage.

How to Replace an AirConditioner Filter on a 2002 ToyotaAvalon

The air conditioner filter onthe 2002 Toyota Avalon is more commonly referred to as the cabin air filter.The filter does more than just regulate the flow of air: It also filters outpollen, dust, exhaust fumes and air pollution. Because it directly affects thelevel and quality of air coming into the passenger cab through the interior airvents, it can compromise the performance of the air conditioning, as well asthat of the heating system, if not changed at regular intervals.

1. Openthe Avalon's passenger's side door. 2. Open the glove box and removeits contents. 3. Locate the stop screw on the right side ofthe glove box, and remove it with the Phillips-head screwdriver while bracingthe bottom of the glove box. 4. Gently swing the glove box downward andlet it hang upside-down towards the passenger's side floorboard. 5. Locate the white filter frame, now visiblefrom behind the original glove box's position. 6. Push the tabs at each end of the filterframe inward to unlock it, then pull the tray and filter assembly out of thecabin air filter housing. 7. Remove the oldfilter from the tray, then install the new one, making sure to tuck the ends ofthe replacement filter under the tabs on the left and right sides of the tray. 8. Reinsert the trayand filter assembly into the filter housing; push it until the tabsautomatically lock the door of the tray into place. 9.

Yeah there is a fuse under the dash board on the driver side. But if you take it out your heater and air conditioner want work. you can remove the dash panel on the passenger side and oil the blow motor and it will not make it noise.

It is a vacuum leak under the hood. If it is a six cylinder, look on the driver side of the intake manifold for a L shaped fitting that usually pops off. If it is a V8 the leak may be near the battery.

the air conditioner filter is inside the a/c line close to the firewall it is normally just inside the small tank itself

Had the same problem. believe it or not i changed the gas cap and got heat all around. something about pressure.

on top of dash board on right side, pop center cover toward windsheld with plastic wedge and you will see 3 t20 torx screws, holding right cover on, pull gently and watch out for speaker wires (certain models) below that panel there are approx 6 t20 torx screws holding another black plastic cover on,
under that is the pollen filter, remove by relaesing tabs on back of holder and reassemble, for future note on right side of dash panel containes ECM and TCM, engine control module and transmission contorol module.

The problem is the air conditioner vent door motors have gone out. There are several of these motors that open and close them allowing the air to move to different parts of the car. Since it is electronic, there are motors that open and close these doors. Unfortunately, these motors are not cheap to replace.
