Question about 1999 Isuzu Rodeo

1 Answer

I own a 99' Isuzu rodeo, fixed blower fan and doesn't work.

I replaced the blower fan in my truck, connected the leads just to make sure everything worked and the fan did not turn at all. I tried to look and see if the resistor went out of it but I am having a hard time trying to figure out if it is or not. Haynes manual says to check continuity through the switch but I cannot get to it that easily. Plus, I tried to check to see if there is continuity in the resistor and I am not getting a signal through my multimeter at all.

I am assuming you checked the fuses for the ac /heater first as you mnever said anything about that.. the resistor block and switch removal can be printed out either by the parts store or dealer service..

look for a fuse or un connected in the engine bay that powers the fan motor.. As for the heat check and bleed the cooling system as you may have an air lock in the heater.

99 isuzu rodeo remote wont work

Flip the battery over and see if the remote will operate with that orientation. You could check the battery to make sure it works.

Also check the contacts. Can be cleaned with Q-tip lightly moistened with rubbing alcohol. (Don't overdo the alcohol, you don't want to wet anything except the contacts.) If there is corrosion, can be cleaned carefully with a pencil eraser or with fine sandpaper. Shake or blow out any debris.

Hope these thoughts help. Good luck

1997 isuzu rodeo blower will not come on relay is good

replace blower motor and resistor at the same time to fix it. The motor may work and may have to much resistance and an old motor will burn up a new resistor.

Subject: 2004 isuzu 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.

1999 isuzu rodeo 2.2L over heating.

The blower your referring to is the unit responsible for moving the hot air out of the heater core so if the blower isn't on the hot air won't come out.
