1990 toyota 4 runner the blower for my heater does not blow all fuses good but is there a connector fuse somewhere

there has to be a short in the system somewhere - use a tester on all area and see if you can find something

Hello, all windows are on the same fuse, there are no fuses for the individual windows, if only one window is not working then it's most likely a bad window motor or a window switch.

You may have a bad resistor or blower motor, a quick test would be to remove the connector from the blower and then turn key on and turn controls to all blower speeds and if the fuse blows then resistor is bad, if the fuse does not blow then reconnect the blower and try the settings again and if fuse blow then blower is bad. good day

When the blower works only on the high setting its usually a bad blower resistor which is right near the blower motor. now you say it would always blow high regardless of the fan speed setting that would indicate probably the climate control unit or a connector problem somewhere. finally it not working at all may be the climate control unit or connection went bad even further. it might have a blown fuse or a bad blower motor in addition to the climate control unit or connector problem .check for power and ground at the blower motor. the power is supplied from fuses and may have a relay also. the ground is supplied from the climate control unit and goes through the resistor to control the fan speed. good luck

Check fuse #14(10amp) located in fuse box under driver steering wheel behind the lower dash cover.
Check fuse#12(40amp) located in fuse box under hood.
Replace fuse(s) if any are blow.

If fuse are good.Check blower and transisto next.
Do steps 1-3 with turn key on
1. Unplug connector and check for 12v at the blue/white wire at the blower motor(2-NAT)
-if there's no voltage you might have a bad relay or open in the wire
-if there's about 12v, go to step 2
2.Plug connector for blower motor and unplug connector for blower transistor(4-NAT). Take a jumper wire and jump the blue/black wire to body ground.
-if blower does not run, replace blower motor
-if blower motor runs, go to step 3
3.check the black wire at(4-NAT) for good ground.
-if you have good ground, then replace blower motor transistor.
good luck

well it could be just a relay for the fan blower motor or a fuse. check all the fan positions..low med high..Its something you can fix but it if got about 600.00 dollars laying around .. take it to the Dealer..lol..Good Luck!!!

See if there is power to the heater motor. If there is, replace the blower motor. If not, replace the switch.

Check the blower motor speed control resistor, and all connections for good fitment.

Alternator ? Is your alternator charging? What type of electrical problems are you having.

the heater blower motor is run through two fuses. the gauge fuse in fuse block 1 and the ac fuse in fuse block 4.
