99 jeep wrangler. No blower fan

I've replaced the blower/wheel. New blower motor resistor. I thought it was the motor since when I hooked up 12V to the old one i got nothing. When I do the same to the new motor it spins. Also I have 12V at the wires (2) grn and blk--- connecting into the blower motor per voltmeter(analog). Any idea why I might show 12V and get no action in motor. How often does the actual switch go out. 10 amp fuse for blower new. Any ideas??

SOURCE: radiator cooling fan 30 amp. fuse keep blowing

The fan may run with jumper wires but if it''s blowing the 30 Amp Maxifuse it's needs a new or used fan motor.It's pulling too many amps.I have almost never seen a fan relay concern.Only other thing you may check is the wiring down near the fan shoud I have seen the 2 wires get loose from the conduit & melt onto exhaust manifold.Hope tHis Helps

Sounds like you need a light tester. I would guess that at least 8 of the wires are speaker + & - the others will be Main power and earth Possibly electric ariel, Memory store and a wire for the anti theft circuit. Assuming the stereo is factory. Any Audio shop can perform a test to clarify the purpose of the wires Wouldnt worry about the blank its probably a position for a newer or different model to yours.

SOURCE: Saturn HVAC Blower Stopped Working

if the resistor card is bad you will only have setting 4 high on the blower and no other speeds, the resistor card is under the passenger side glove box by the center console way up there, i think its a phillips head,if i remeber right not too hard to get to,,, if no high speed then the fan motor is bad,thats under the wiper cowl under the hood,u gotta remove the wiper cowl to replace it

SOURCE: 1995 Saturn SL2 DOHC motor No start fuel injector issue.

i would have to say first check the fuel injectors fuse in the under hood fuse block if blown replace it,sometimes the fuel injector harness rubs thru anywhere from where the harness comes thru the firewall all the way up to the injectors,,,if fuse is good and no bare wires to injectors,check the wires to the ignition module,,,,and if all checks ok,i would replce the ignition module,,you could have spark from it but it could not be sending the signal back to the pcm to fire the injectors,,,and if all that fails try a pcm,but i think youll find it before that,,i seen this 3 times and each time it was a wire rubbed thru near the fuel rail and it grounds out and blows the injector fuse,
hope this helped

My 1998 Jeep Wrangler Heater Motor only has one speed High. Nothing on any of the lower ones, no matter on ac or heat. What could be the problem?

This is 100% the Blower (Fan) Motor Resistor located near the Blower Motor.
This is a very common problem with Chyrsler, Dodge, Jeep and Plymouth. The key symptom is the Fan only working on High.
This is very easy to access and replace.

Let me know if this helped....

2001 Jeep Wrangler heater blower stopped working

Yes I would go with the switch, BUT, does it have a resistor bank? That is, how does it reduce the speed? Many systems use resistors to lower the speed. Burnt or bad connections can cause this as well.
You can test the blower motor by connecting direct power from a source like the cigarette lighter if you are handy.
Most of the time the lower speeds konk out but the high speed continues to work this is the resistor bank that goes out.

I have a 1999 Jeep Wrangler and the heater fan stopped working for all the fan speeds. The fuses are fine. How do you know if it is the blower resistor or the blower motor?

If you bypass the resistor pack and connect the motor directly to the fused 12v supply then the fan should run at maximum speed. If so, it's the resistor pack that's blown: a very common fault on a huge number of makes and models.

98 Jeep wrangler, fan/air won't cut off

Replace the blower motor resistor. You can unplug the fan till you get one. Usually located behind the glove box.

Wrangler jeep heater/AC fan

Usually, when the fan works only on high speed the issue is with the blower motor resistor. It will be located under the dash close to the blower motor itself. It will have a multi-wire plug and feeds signal to the blower motor. An updated resistor maybe available in which case a slightly larger hole will have to be cut for the new resistor. This is not a difficult proceedure, only a couple of screws are holding the resistor in place and most resistors are resonably priced. I recommend you buy the resistor at the dealer, this is a case where you get what you pay for.
Good luck, hope this helps.
