Question about Jeep CJ5

1 Answer

I have a 1971 with a V6 motor. I am trying to replace the heater blower motor. My old motor has two wires...one orange, one yellow. The new motor has three wires...one ground, one black, one orange. It has both black and orange listed as hot. What do I do?

Last time I looked, black was always the ground... But, been wrong before.I'd check with parts guy to make sure you have the correct motor. If it replaces original design there is usually a sheet with wire re-route diagram. If not, use a volt meter to determine which wires are carrying voltage in the vehicles harness connector. One may have less volts than the other... I would assume the one closest to battery voltage is high speed. one should be ground. If both carry voltage then the case is ground.(usually in this case there is a spade terminal on one of the attachment screws, and a seperate ground wire.) If your new motor has three terminals, it's likely that one is ground, one low speed one high. (though I can't remember ever seeing this arrangement.(speeds usually controlled with resistor block) Again, if this is the only motor available, at worst, I'd tie both power leads from the motor together (making sure that one lead is not a ground) and connect them to the harness spade that carries 12v, make sure there is a good ground, and use as is. But, do some research first.
Good luck

    Just checked with NAPA online and the blower motor shown has two leads (for non-a/c vehicles) cj5 with v6!!! Definitely check with your parts guy before driving yourself crazy trying to follow my instructions (but if you must, note: I work spastically but write down results before making any decisions as to install or any mods to install)

1983 Chevrolet C10 Silverado: The AC compressor and heater blower motor fan will not come on.


The brown wire at the speed switch is the power wire. Powers is then directed to the blower motor resistor throught the orange, lt blue and yellows wires. The blower motor receives power through the orange wire. Check for power at the fuse with the key on. If there is no power the problem could be the ignition switch or the wiring in between the switch and the fuse block

Blower motor only works on low and medium on 2007 dodge nitro


You replaced the resistor and WHAT relay? The blower motor circuit on a 2007 Dodge Nitro does not use a relay.

The blower resistor gets it's power from the A/C - heater control unit.

If you check for voltage at the blower motor resistor connector (Key on, relay disconnected), the DARK BLUE/GREY wire should be hot when the control switch is on HIGH. The DARK BLUE/VIOLET wire should be hot with the switch in the MEDIUM 2 position.The DARK BLUE/ORANGE wire should be hot with the switch in the MEDIUM 1 position. The DARK BLUE/BROWN wire should be hot with the switch on LOW.

If any of these are not as stated above, then you either have a bad A/C - heater control unit, or faulty wiring between the control unit and the resistor.

The heater in my 2000 wrangler does not work. There is a connector with black/white, yellow and orange wires hanging down under the blower motor under the glove compatrment. Where does this connector...


You will see a round plastic blower motor housing underneath the passenger dash approximately 6-7 inches round, plug the connector back into it and you should be good to go.Let me know if it works for you or if you need further assistance

Heater blower only works on high. Replaced the resistor no difference.Checked fuses OK. What else could it be.


The resistor has a thermal limiter in it, if its bad, it cannot be reset. The blower motor may be bad causing high amperage, burning out the limiter. At the resistor,Ck if there is power at the GRAY/BROWN and GREEN/WHITE, and BLACK/GRAY wires, they should. If not CK the Violet/Orange wire, it should have power.If the Violet /Orange wire has power, but the others do not the limiter is bad and it needs replacement (resistor) If all have power, then when gounding each wire (except the Violet/Orange wire) the blower should come on

Blower motor will not blow fuse relay motor are ok


it could be that the motor itself is bad there is a relay inside the motor as well give these websites a try www.alldatadiy.com and www.autozone.com if it was me i would checkout one at a good salvage yard give this website a try to find one close to you give this website a try www.junkyarddog.com wish you the best of luck Michigan Man.

The blower motor for the heater/AC does not work after replacing it. All fuses are ok


OK, history would be nice. What a/c do you have, Manual or Auto/Electronic? All Speeds? Why did you replace the motor. If the fuses are ok, did you check for power at the motor? if it has power and ground, it HAS TO WORK, or the motor is bad. If you did not check for power, then if you have Manual A/C, Turn blower switch to HIGH SPEED, check the PURPLE wire (at the motor), if it does not have power, then check RED wire at the BLOWER RELAY. The RED wire should be HOT AT ALL TIMES. If the Red Wire is HOT but the Purple wire is not, then check the ORANGE wire at the blower relay, it should be hot (if the orange wire is not hot you may have a bad blower switch ). If the RED and Orange wires are hot, then the relay may be bad, You can by- pass the relay to see if all is ok but connecting the RED AND PURPLE WIRES. The blower should run at high speed. I dont want to look at the Electronic A/C, its more complicated and I dont want to waste time if thats not what you have.

I have a chevy colorado. only the high spped fan works. there are no indicated fuses for the fan system what can the problem be


TRY THE BLOWER MOTOR RESISTOR FIRST. POWER GOES THROUGH THE BLOWER THEN TO THE RESISTOR AND THEN THE CONTROL MODULE TO GROUND.

THE RESISTOR IS ON THE BOTTOM OF THE HEATER CASE ON THE PASSENGER SIDE. USING A TEST LIGHT ATTACHED TO GROUND TOUCH EACH OF THE TERMINALS ONE AT A TIME WHILE SWITCHING THE POSITIONS ON THE BLOWER CONTROL. IF THAT WORKS YOU WILL HAVE A LIGHT FOR EACH WIRE IN EACH POSITION ON THE DIAL. THE RESISTOR IS THE PROBLEM THEN.


RESISTOR WIRE COLORS
LOW = YELLOW
2 = TAN
3 = LIGHT BLUE
HIGH = ORANGE

RATE ME, PLEASE

2001 sunfire blower motor wires


You'll have to determine which wire from the harness is plus and which one is minus. Same for the terminals on the blower motor.

If the wires are connected backwards, the motor will spin backwards and will blow very litttle air because the blades on the fan are "pulling" air instead of "pushing" it.

An easy way to do this is to hook it up one way and see if the fan blows air -- if it doesn't, hook it up the other way.

I would expect the harness-orange wire would go to the motor-red wire -- try this first.
