sound's like a earthing problem , try a continuity test from blower LIVE to chassis , if get continuity then def got a wiring problem , very difficult to diagnose without seeing vehicle , get a auto electrician

Ac will not work on high in 2004 isuzu rodeo


What is near the motor? This isnt working on HIGH. So its not a resistor. If that is what you are talking about? High isnt connected to a resistor. Its direct power so what would changing the resistor do if the only possible problems are fuse, relay or switch? If it worked on HIGH and not setting one through three then yes it would be the resistor on the ac blower motor if it is still powering on when tested on the low settings.

The heater / blower in my 1992 dlx has stopped working all fuses ok


Hello hfg.

1. First of all, tap the blower motor gently to see if it starts it. If it does, the brushes or the armature in the motor are worn- replace the motor.
2. If that doesn't help wiggle the connector on the motor and the blower motor resistor. There may be burned or loose connections.
3. If you have power on fuse 7 with the key on, then check for power at the blower motor on the blue white wire. If no power on it you have a break in the wire between the fuse and the blower.
4. Next, check for power on the blue black wire. If there is power there that proves there is continuity through the motor(that's good), if not, replace the motor.
5. The blue black wire then goes to the blower resistor. this resistor gives the different blower speeds.
inside the resistor there is a thermal fuse. It isn't replaceable, only the resistor as an assembly.
If the thermal fuse blows it may indicate that the blower motor is beginning to wear out and draw too many amps. And then you may need to replace both the blower and the resistor.
Check with an ohmmeter across the thermal fuse. If it is open circuit, replace the resistor and the blower. If you don't replace the blower it may blow the new resistor again.
6. If it all checks out to this point, ground the blue/red wire at the resistor. If the blower comes on the problem then becomes the blower switch or a break in the wire to the switch.

Whew.. Hope this helps solve the problem, my fingers are sore..Ha.

Thanks for using FixYa.

1999 Isuzu Trooper Problem with Blower Motor, FUse Box, and exter


Did you find out a solution to your problem? I have a 1996 trooper that is showing most of the same symptoms that you have. I'm curious as to your fix. Was it simply a bad ground?

2003 Suburban heater fan will not working.


three things left to check,
using test light see if you have power at motor with key and switch on,if you do replace motor,if not locate blower motor resistor it will be close to motor,check for power going in,last is the heater control assembly

Blower motor on 96 Isuzu Rodeo does not blow on any speeds, fuse is good. I read if blower motor on works on high only it is resister, and if works on all speeds but high is relay.. so does blower motor...


if fuses are good, check for power at blower motor, when truck is running and a/c on. the resistor and the switch provide ground, so the blue/white wire should have power, and the blue/black wire should have NO power, if it does have power, then most likely the resistor is bad. if it has no power and the motor doesnt run, the motor is bad.

Subject: 2004 isuzu rodeo...my ac/heater blower is not working


The resistors are in circuit only on the lower fan speed settings.
On the highest speed setting, power is switched directly to the fan motor.
Check fan power supply fuses,
Check power is available to the fan when high speed selected.
If all above OK, apply power directly to the motor to verify fan motor runs- if it doesn't the motor may need replacement/repair.

1997 isuzu rodeo problems with the blower motor and resistor how do you test them both


You can test the blower motor by connecting a positive and negetive wire directly to the 2 terminals on the motor.
As far as the resistor goes. If the blower motor only works on high fan speed then the resistor is bad. If it works on all speeds except high, then the relay is bad. Good luck. Hope this helps.
