Hey Jeep folks!
I have a 2005 Liberty and the blower only works on 1, 3 & 4. on 2 it does absolutely nothing. Was reading about something that I could maybe replace behind the glove box. Could someone provide more details please? Let me know if you need any further details.

Thanks,

Its called a Heater Blower Resistor and yes it is located behind the glove box near the blower motor.
HVAC Heater Blower motor resistor
Part Number: JA1464 (Duralast AutoZone)
OE # 05139719AA; 05066552AA; 05066554AA; 05066553AA
Dorman 973-025
Standard Motor Products RU-352

It is a common part that fits many Mopar vehicles and is available at most parts stores... :wink:
This UTube video does a good job of showing you how to replace the resistor in a Jeep Liberty! :D >https://www.youtube.com/watch?v=LeVJP9hy5fA

WWDiesel,
Thanks for the reply and video link (Looks easy)! For $16.99 definitely does NOT hurt the wallet. Based on what I've said do you think that this is a good place to start?

Absolutely!!!! I will be real surprised if it does not fix your problem.... :roll:

It wouldn't hurt to replace the resistor. However in my experience stepped resistors for things such as fan control fail so you have high speed or off. Nothing in between. I'm thinking your problem is elsewhere.

Twice I've replaced them. In both cases one out of 4 settings went, then another, then everything but hi.

All blower speeds except HI go through the resistor. Hi speed bypasses the resistor and puts 12 volts straight to the blower motor....
And yes, you can lose one of the lower speeds without losing the others when a circuit in the resistor fails... :wink:

Definitely! We only had the first one not working for example. The rest worked fine.

I went with the Duralast JA1464 so if it fails again they should replace it for free under the warranty.

**UPDATE**
I bought and tried a new blower motor resistor and got it installed. No dice......same thing, number 2 still doesn't work while all others do. :(

I'm starting to think that HER_CRD may be correct in this case.

Any other suggestions?

Time for a volt meter diagnosis to see just where the failure is at!
Next most likely part that can fail is the rotary blower speed selector switch, but without a proper diagnosis with a voltmeter, an accurate prognosis is just a best guess... :roll:

WWDiesel,
Thanks for your help. You had said earlier "I will be real surprised if it does not fix your problem". So, when I installed it that night and seen it didn't work I was disappointed and left the part in over night. The next morning I was ready to re-install the old part back into my Jeep with my intention to return the new part back to the Auto Parts Store. From my work bench I picked up what I thought was the old part from my Jeep and thought to myself for an old part this looks new (hmmmm). From my Jeep I removed the installed part out (Which looked used), after looking at them I knew exactly what I did. I then installed the "New" looking part and once put all back together, it tested good! I had the blower on all 4 settings and they all tested good.

So in short, yeah I pulled a dummy/novice move here. *Sigh* :oops:

I'm set and this part fixed me up! Thanks for dealing with my naivety here.

Thanks,
2005 KJ Owner

Heck we all make mistakes! To err is human!
Very glad I was able to help and it turned out to be the correct diagnosis! :wink:
Advise: Next time, throw the old part in the trash before opening the box with the new replacement part... :ROTFL:
