Question about 2005 Toyota Tacoma

1 Answer

My AC/Heater fan blower just works on high, but when I hit a bump big enough to cause a significant vibration, I can use the other speeds (low, medium etc...). If I hit the bump again it'll just work on high. Any recommendations on how to fix this? I'm thinking it's the soldering that was used but don't know how to locate the glitch. I drive a 05 Tacoma TRD Sport. This Toyota has given me too many problems, probably last time I buy a Toyota. Tks

    thanks speedypablo. So I went ahead and fixed it: found out that what happened was that apparently there might have been a loose connection and one of the pins in the male connection of the resistor connection was dark in color instead of the typical silver (sort of the color of a blown out fuse). I went ahead and got a pin driver, a small piece of high grit sanding paper and cleaned the connection on the male and female part. I put it all back together and vuala it worked. I figured that since the resistor looked a bit "old school" chances are that it's been working for a while for Toyota so chances are the resistor was still good. Here's a pic of the resistor since it's typically time consuming to find it on other pages.

Wiggle the wires behind the control unit to see if maybe there's a loose wire. If that does not work, then try tapping the climate control switch, if it works then you know it's your switch that needs to be replaced. If you want to fix it yourself, just take it out and dissasemble it and clean the unit with alcohol or nail polish remover and try it again on the part (knob) that makes contact with the board. a new unit is very expensive.

AC/Heater Blower Fan in 1990 LS400 works intermittently


Due to the age of your vehicle, the brushes in the fan motor are worn out. you will have to replace the fan motor, it is not serviceable.

I will assume the heater fan also doesn't work on low. You will need to replace the fan speed selector switch

My 2002 gmc serra has a issue with the ac and heater the lights turn on but no air I hit a bump and it will turn on for a second but it stop blowing air cold or hot what could it be....


the blower motor resistor relay are bad about shorting out and melting the connector causing a loose connection and when you hit it or a bump it'll make connection and work. look under the passenger side dash and you'll see two wires coming from the blower motor. trace those two wires to a little black box with somemore wires pluged into it and try to unplug the other connector that has about five wires coming from it. turn your key on and your a/c with the blower speed set on high, try moving those five wires if the fan blows and quits, then this is the problem. you'll have to replace the resistor and the wire connector.

Fan for Ac and heater does not work on 2000 T & C van. It only works on low or high. All other settings are the same as low


replace the resister module for the fan,this is what controls the speeds,and most of the time the blower motor is what causes the module to go out,

Heayer doesn't work


The resistors provide resistance in the circuit, dropping voltage to the blower motor to slow the motor speed down. On high, the blower receives full voltage through the blower relay.

If you had High but no other speeds, then the resistor pack is usually the culprit. If you have all other speeds but high, the most common problem is going to be the blower motor itself, relay, or the switch panel.

You can check this by turning the fan speed to "high", unplug the blower motor, and check to see that you have roughly at least 12v at the plug. If you have 12v, that means the switch panel is activating the relay and the relay is working. Over time, heat kills the magnetic properties of the magnets inside an electrical motor. Without enough magnetic energy, you may not get enough opposing force to spin the rotor full speed when the windings energize, but still enough to spin at lower speeds.

Another thing you can check is the connector at the blower motor and the switch panel. Sometimes these will heat up, start to deform, and cause a bad connection. The bad connection may be able to handle the lower current draw on low speeds, but the higher resistance from the bad connection won't be able to handle the higher current while in the full speed position.

Hope this helps, keep me posted. be glad to help you get your heater working again soon.
