Air con not working in 93 corolla seca.

if air con is not working it could be the clutch in the ac pump, if you dont use the air con much or use it alot you can either have a seized clutch or a work clutch, without the clutch engaging the pump will not work and not flow around the system, when ac is engaged the idle on the engine will drop slightly.

This is Toyota Corolla Axio 2008 model. My A/C isn't working, So I decided to check the Dashboard fuses for A/C. There is no diagram. Can Anyone Help Please?

With headlights on, try to start the car.
While engaging the starter: Do the lights dim? Do you hear anything? If so, what do you hear?

There could be few problems, if the gas is too low or too high the compressor will not work, maybe the compressor clutch is not engaging. why don't you power the compressor from the relay and see if the compressor works or not.

Hi,
it is generally because the air con heat exchanger has to be cooled in order for your air con to work correctly and cool the interior of your car.


The air conditioning utilises a gas by the name of freon. This gas is pumped around the air con system by a compressor. The gas, going through the aircon cooler or heat exchanger, starts to cool down. Depending on the system layout, the gas is forced through a very small aperture situated after the cooler. It reverts to a liquid, passes through the matrix in the car, a fan blows the interior air of the car through the matrix. The fluid picks up the heat, and cooler air exits the matrix and, (hopefully) cools the interior of the car. This endless cycle is repeated as long as the air con is powered on.

Hope this brief description will suffice.

Squealing is associated with belt slippage. 1) ensure that the belt is tight - at the longest distance between two pulleys it should be possible to twist the belt by about 90 degrees only. 2) with the engine running check funder the hood or the free running of the pulleys. a) Ask a colleague to engage the power steering from lock to lock and see if the power steering pump pulley does not cause slippage. b) set the air con to low and watch what happens when the compressor pump solenoid engages. If the belt begins to slip on the air con compressor pulley it is likely that the compressor is beginning to fail by seizing up. In that event preserve the belt simply switch the air con off and pray for cooler weather until the compressor can be overhauled.

Hi:

You should verify that your AC system still has a full charge of refridgerant, and if it does,
The problem is most likely the AC clutch assembly on the front of the compressor.

Since the dash light works, and the fan turns on, there is power to the system, but the compressor won't turn on if the pressure switch says the charge is low, and if you turn the switch, and someone can hear a click of the compressor clutch solenoid, but no air, the clutch assembly is probably the culprit

I think,on this vehicle,there is a w o t switch.This is WIDE OPEN THROTTLE ,if so it may be bad.Also look for a short in the low side clutch cycle switch.I am not familiar with this model car,but basically they should all work on the same principle.If I can help,let me know.>>[email protected]

It may be low on refrigerant if the pressures are to low, the compressor will not engage.

THERE IS A FUSE,HOWEVER MORE COMMONLY YOUR SYSTEM IS LOW ON R12 AND CUTOFF SWITCH IS ACTIVATED. TRY JUMPING THE CONNECTOR OUT OF THE ACCUMLATOR,THERE SHOULD BE A SWITCH ON IT,PULL CONNECTOR AND WITH VEHICLE RUNNING GET A PIECE OF WIRE AND INSTALL THEM IN BOTH FEMALE TERMINALS. IF A/C CLUTCH ACTIVATES SYSTEM IS LOW OR BAD SWITCH OR BAD FIELD COIL OR CIRCUIT DAMAGED
