Question about 1991 Toyota Previa
We know it is the fan speed resistor,but are unable to find it,is it uder the hood on pass side behinc the fan?
Let the engine run, turn on heater, and get out and open and close the hood a few times, slamming it. If it starts to blow, you got a bad heater blower motor, with bad brushes. The resistor you are talking about, is about the size of a pack of cigarettes, with 2 screws, and has some white plaster looking stuff on the other side. I would replace that too if you get the blower out, because I do not think it will come out without first removing the blower. Resistor is about $20-25.00. Blowers usually go bad between 120-140k. I change the resistor every other time. The switch goes bad too, and it will only work on every other position. To change that, disconnect the battery, and take out the fuse box, and all the faceplate screws, and that will get you started. The switch from a dealer comes with the led lights and is $40. If you buy aftermarket, you may not get the lights. I have 2 1991 models, one with 360k, and one with over 500k. This has been my experience with the heating system.

The ballast resistor for the heater fan is just under and behind the fan motor and to the right facing towards the rear of the van. The resistor is on the inside but can be taken off from the outside by removing two screws and disconnecting the wiring. I took the entire fan housing off to find it but I think it might be possible to get the resistor out without removing the fan housing. To help locating the resistor, it is just above the bottom right (facing towards the back) bolt of the six bolts that hold the fan housing onto the firewall.
