Where is the blower fan located in a 1992 Previa?

Answer 1

It is under the front hood, at the bottom of the cabin air intake plenum. You can't see it without removing a cover at the bottom of the intake, air management plenum. To replace it, you have to remove the the fresh air intake, the Power Steering resevoir, the antifreeze resevior,the recirculating air intake cable. It is necessatuy to also unbolt the air management housing from the firewall. The blower motor is upside down coming in from the bottom under the cover that was mentioned earlier. The speed resistor block is also under that cover. The power wires run through the intake feeding in from behind the fuse compartment in the top center dash compartment in the cabin. It is difficult yo disconnect the wires at the junctyion but it can be done. Reconection is easier. It took me a three hours to replace the speed resistor block which is located in the same area as the blower. A $30 part. I had a dealership replace the blower motor a year ealier for $438. (the motor cost $125) My parents owned the Previa at that time. I inherited it and found that the blower only worked on extreme low and extreme high speeds. That's when I went in myself to swap the resistor. I still don't know why the dealership didn't do it when they swapped out the blower.
