SOURCE: have a 1993 toyota pickup 4 cyl heater blower

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.

BLOWER SPEED CONTROL SWITCH 1kbron_27.gif

Switch Position (1) Continuity Between Terminal No.
  1. OFF (1)
  2. LO 5 & 6
  3. (D) (2) 1, 5 & 6
  4. (D) (3) 2, 5 & 6
  5. HI 5, 6 & 8

(1) With switch in any position, continuity should exist between terminals No. 3 and 4 for heater control illumination. With switch in OFF position, continuity should not exist between any other terminals. (2) Circle (D) closest to LO position. (3) Circle (D) closest to HI position.


HEATER RELAY
  • 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.
BLOWER MOTOR
  • Disconnect blower motor wiring harness connector.
  • Apply battery voltage to motor side of connector. Motor should operate smoothly.
  • If motor operation is not smooth, replace motor.

BLOWER MOTOR REMOVAL & INSTALLATION
  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.

Heater Relay is located on the Relay Block, Front Right Side Of Engine Compartment
Good luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

The low/med/high fan switch on my 1985 Toyota pickup is no longer working, How do I replace the heater fan blower switch?


Hi,
Don't go there just yet ! Most heater motor speed problems relate to the heater resistor ! It's located in the ducting close to the motor assy and usually has 4/5 wires on to it and a 2 screw fixing. This componant must be cooled (hence air duct location) and is solely responsible for motor speeds ! You can check motor fan by test lamp/meter ! Good Luck

Replacing heater blower motor


this is not a problem with thw switch or motor. There is a resistor that is mounted inside the dash on the pasenger side that controls the speed of the blwer..these have a tendency to burn up after 10 years or so... replace the resistor, and you will be fine!  http://cgi.ebay.com/ebaymotors/Toyota-Truck-A-C-Heater-Fan-Resistor_W0QQcmdZViewItemQQcategoryZ33548QQihZ016QQitemZ260344846266QQrdZ1QQsspagenameZWDVW#ht_500wt_1230
