1993 previa Blower Motor Resistor location - 1993 Toyota Previa

SOURCE: Where is blower motor resistor

HI....
The BLOWER motor resistor on a Toyota Camry 01.
Is located Behind center right side of dash.
ON blower housing.
If you vehicle is equipaded with protection cover.
Just you need to remove the cover. and will see the blower resistor.

I hope this information work for you.

Thank you for use fixya.

Two bolts a little neck twisting 5 mins...
Look under the dash follow the wiring from the blower any two of them will lead you to the resistor. It's in the air box about.

If your Previa's low/medium speeds on the blower (ac/heat fan) have stopped working, but the high speed works, you most likely have a problem with your blower motor resistor. Here's how to access the resistor. These directions may be slightly incorrect since I finished this procedure about an hour ago and I'm typing this from memory. But they should get the job done. It took me about 30-40 minutes to do this from start to finish:

Remove cabin air intake duct (two philips screws)
Remove one bolt holding antifreeze reservoir in place, move reservoir aside.
Remove two bolts holding brake fluid reservoir in place, move reservoir aside.
Unsnap recirculate/fresh selector cable from blower housing (on vehicle-left side of housing)
Remove angled metal arm from vehicle-right side of blower housing (attaches to firewall with nut and to housing with bolt).
Remove two bolts (at vehicle-front of housing) that hold the upper and lower blower housings together.
Remove nuts on firewall holding upper blower housing in place, and begin to work upper housing out of vehicle, disconnecting the 4 electrical connectors as needed (2 connectors are on top and 2 are down beneath the blower housing).
Remove nuts on firewall holding lower blower housing in place, and remove lower blower housing from vehicle

Look on the lower blower housing, on the side which was facing the firewall, and you'll see a white ceramic block (approx 2-3 inches long). This is the blower motor resistor. There are 2 contacts on the resistor that should be joined by a springy curved band. If the band isn't bridging the two contacts, it's likely that the soldier has melted/broken, and this is what's causing the low/med speeds to not work. Solder the band back in place and this should correct the problem (it did for me).

Hi!
To find out if your problem is the blower motor or the blower resistor or switch perform the following tests.
BLOWER RESISTOR

• Remove resistor from vehicle or disconnect resistor wiring.
• Using an ohmmeter, ensure continuity exists between blower resistor terminals No. 1 and 4. See Fig.
• If continuity is not as specified, replace resistor.

1. OFF (1)
2. LO 5 & 6
3. (D) (2) 1, 5 & 6
4. (D) (3) 2, 5 & 6
5. HI 5, 6 & 8

• Remove heater relay.
• Using an ohmmeter, ensure continuity exists between heater relay terminals No. 1 and 3, and between terminals No. 2 and 4.
• Ensure continuity does not exist between terminals No. 4 and 5. If continuity is not as specified, replace relay.
• Ground terminal No. 3, and apply battery voltage to terminal No. 1. Ensure continuity exists between terminals No. 4 and 5.
• If continuity is not as specified, replace relay.

1. Disconnect negative battery cable.
2. Remove glove box, if necessary.
3. Disconnect blower motor and resistor connectors.
4. Remove 3 screws and blower motor.
5. To install, reverse removal procedure. See Fig.

The resistor pack is almost always close to the blower. It needs air moving across it to keep it cool. It is usually installed into the duct with two small screws. It has a connector with about 5 -6 wires, and is about 3/4 inch wide, and about 3-4 inches long. Some can be a little difficult to get out due to clearance, and their shape.

Also, it could be the fan speed switch that's giving you problems.
