Sound like you have a bad blower resister some have a module next to the fan on the passenger side by your feet there is a resister that is inserted in to the blower box or black box that is a module that is inserted that neads to be changed

Yes, pull the glove box out and the resistor pack is right there in the lower right corner of the opening. There are 2 small bolts holding it in. It's about $15 and takes about 5 minutes to replace.

Rpm1998 sounds right...I had this problem before where the fan speed only changed on high and low but not in between...like he said you have to get up behind the passenger side dash from underneath...there's a black square that inserts into the side of the blower motor that needs to be replaced...mine had obvious signs that it had blown as it was slightly corroded

good luck!

I have a 2006 erangler X And the heater fan control low speed does't work. I dont know where the resisters are. Need help!


They are near the blower motor as the air is used to cool the resister, usually on the bottom of the blower housing.

'00 Jeep Wrangler with no heat and AC not blowing


Ok, if you are trying to use your AC and its not turning on, odds are your refrigerant levels are low, the system will not turn on when low fluid levels are present so the system doesnt burn up the compressor.

If your blower motor is not operating, you may have a fuse blown that needs to be replaced, or the control chip that plugs into the blower motor (for fan speed settings) has burned up (easy fix).

If your climate control is not throwing out heat when you change the settings to hot, you have a leaky vaccume line and the vaccume pressure is not strong enough to open or close (depending on setting) your blender box. Although typically when a vaccume line springs a leak you will have issues with your selector switch as well (defrost, vent, floor)

Also pay attention to your temp gauge to make sure the thermostat is operating properly, and the engine is not over heating ro getting excessivly hot! If it is, then you need to replace the thermostat ($8 part)
and go from there. Also you should check your heater core, if it gets clogged or has restricted coolant flow, your system wont have the heat it normally did (if any) when it worked properly.

This is just a quick summery of the area's you should be looking into for the problems you are having! thanks for using Fixya.com and good luck, I hope I have helped make resolving your problem alittle easier

Heater blows cold air


the electric motor that open the heat door looses electrical connection there by the door stays on cold / it is located under the a/c heater assembly / which requires removing the whole dash and heater assy// also bleed all air out of coolant system
there are three doors / 1/ a/c heat 2/ mode /defors 3/ recurculation dodgeboy6069@yahoo.com
