Toyota Previa fan blows but no air.

When you turn the fan on for the heater/air conditioner it turns on but acts like the air flow is blocked at the fan. You can feel air through all the vents when you change the position of the vents but the fan does not increase air flow when turned on. You can hear the fan blowing. What could be blocking the fan from pushing the air? Thanks.

It could be that; the FAN MOTOR works but the fan-wheel is not turning. This usually happens when the center spindle of the fan-wheel RUSTS and eventually loses contact with the actual wheel itself.

SOURCE: 2001 toyota corolla blows 7.25 fuse when turn on ac

I unplugged the wire, replaced the fuse and started the car. Then, I turned on the ac button and the fuse blew. Do I need to replace the whole compressor with ac clutch or just the ac clutch? Thanks so much.

SOURCE: A/c problem.

jasonjacob1 is right. If the air from the A/C is not cool, the only cause is low or empty refrigerant. This means that the gas that your vehicle uses to produce cool air is gone from the system. The solution is not to recharge the system but to locate and fix the leak, then recharge the system.

SOURCE: '03 Toyota Corolla- Air Condiotioner making noise...

I've been looking into an A/C problem for my 2004 Pontiac Vibe (which is basically a Toyota). Found something that might help you. Evidently there was a service bulletin (NOT a recall) about this model's M/G CLT relay in the air conditioner system - many of them have proved faulty! That relay is in the fuse box under the hood near the battery. Basically the relay just has to be replaced. Cost of part is around $70. Hope this will help!

SOURCE: 2005 Toyota Corolla air conditioner is cold but

The air flow does not 'increase' with the recirc button pressed. The fan motor blows at specific speeds, no matter whether fresh or recirc is selected. The recirc feature is there so that you do NOT admit 'fresh/hot' air from the outside into the AC box. In short, the recirc feature is to re-use, or, recirculate the existing air in the car. When it is properly working, on a hot day, the recirc selection should drop the internal temperature at the center air vent about 6 degrees lower than with the fresh selected.

check your blower motor under the passenger side of the dash, round plastic box three screws pull it out something might have fallen though your cowl and chewed up the fan blades. as for the ac your r-12 is probly empty or has a leak bring it to a local garage and have them flush and fill your cooling system. heater would be your thermostat not openig properly, by far your cheapest fix under ten dollar part.

I have a 1992 Toyota Previa. The heater stopped blowing air. For the last year the fan would only work on the highest setting.... now nothing. Is it the Blower motor, fan relay, or Switch??? Any idea?...

the last year, your blower resistor has been bad, now your motor is bad. rap on the motor and see if it start to run, if so, replace the motor and the resistor.

No air coming out of the vents

It sounds like the heater motor may not be operating. When you switch the heater fan on can you hear the motor running? If not then it may have blown the heater fan fuse, check the fuse's and then try it again. If the fuse is ok then it could be a faulty switch or fan motor.

When I turn on my 2004 toyota highlander air conditioner the fan on the motor sounds like it is running, where it has never done this before. what could be the cause?

When you turn on the AC pop the hood. If it has an electric cooling fan or an electric fan infront of the radiator and condensor then its normal for it to come on. Without air flowing through the core the AC will not blow cold air. You just may not have noticed it before, or the fan is wearing down and producing a bit more noise than before.
