1989 SUBARU JUSTY 1 2L L3 Blower Motor Control Module Resistor RockAuto

its on the main power supply board.
and there are 2 fuses.
thanks

A defective HVAC blower motor controller, or relay/micro switch in the control panel may cause the heater/AC blower motor not to work.

My 93 xj6 doesn't blow or anything but I found that if I kick the blower under the string wheel. It comes on. Then it's blowing cold on the dash and hot out the center counsel. Where do I kick to fix that? There are buttons that light up by the steering wheel. That look like the seat heater button. Is there a way to choose to make the thing blow cold in front and hot in back? 989-657-2563

The resistor that controls the blower motor. it is a small gadget that has a 2 or 3 wire plug . Replacing the resistor should fix your problem. It is on or near the blower motor. Under the dash. Not easy to remove . But it can be. Please give thumbs up if helped.

its the computer behind the radio,they have a bridge connection in them that just passes the current straight through it doesnt do anything other than to confuse .run a feed from the heater fuse on either side of the floor well to the appropiate blower ,like right hand fuse to right hand blower and left hand fuse to left hand blower and it will all work ,speed control included

replace the blower speed control module located near the blower motor

check the fan speed resister block... located under the dash in the duct work near the fan. i may have failed

Hi
Did you check the vacuum to the new heater control valve, they usually give trouble.
Fuse for fog lamps will have nothing to do with the heater system.
Good Luck!

It more and likely is the servo motor (s) that are the problem, when you turn hot to cold and defrost they cycle the vents in conjuction and are a common failure on this model.
The ones that fail are accessible if you remove the right underscuttle panel and the glovebox.
Black motors with a double wire, usually have a red connector on the end.
