    My wife has an 02 Liberty that she loves. Been problem free through 73,000 miles except for the blower control.
    This is a 4 position switch that only the fourth position works on. Does anyone know if this sounds like a switch, or is it something more complicated? If it is a switch, I can probably change it, if not probably a trip to the dreaded dealer. Thanks

    I'm not sure if it was on this board or the Wrangler board but I just read someone stating they had the same problem. Turned out to be a resistor in the circuit used by the first three settings. The highest setting bypasses the resistor in the circuit which provides the full fan speed. Good luck.

    Hey, thanks for your help, I am still not sure if this is something that I can tackle or a dreaded dealer item.

    I have the same fan blower '1,2,3 switch position not working' problem. Did you find where the defective resistor is located?
  • drvbdrvb Posts: 2
    I discovered a blower relay in the box under the hood just ahead of the battery. When removing it, it also killed the #4 blower operation, so I'm on the right track. Can anyone tell if by replacing that relay will solve the problem, or do I have to keep searching to find the resistor associated with the lower speed blower operation. By the way, the system is developed by Johnsons Control who seem to be favored by Chrysler.
  • It seems like the fan blower switch problem is more common than I thought. I have the same problem, except the 3 and 4 switch settings work on mine.

    I sure don't want you digging into your dashboard on this so please check it out before following my guess...Just something to consider, though...

    I remember working on my old '88 Chevy Beretta for a dashboard light problem and was interested to see the back of the blower fan control switch had different-sized resistors across the contacts on the back of the switch. Is it possible that's where the blower fan control resistors are located?

    I sure wish I could remember where I read that about a resistor controlling positions 1-3 and 4 was not in series with the resistor. You might do a search in the Wrangler board or the Liberty board...I was pretty sure someone had the answer to what you were looking for.
  • I had the same problem, #1,2. I found a web sit that has online service manuals ($25USD). The resistor is located behind the glove box. Open up the glove box, then on each side, you should see the clips that stop the glove box from opening up all the way. Squeeze them towards each other and the glove box opens up. (empty glove box 1st). the resistor is towards the right. There was a red locking clip on the bottom, getting this to come out was the biggest problem, it does NOT come off, just out. then remove the cable connections, then two bolts (5/16). It took me about 30 minutes total. Mopar part number on the bag 1-05139719AA. Cost was $23.63 CND with tax.

    Thanks for the help. I was able to replace this resistor in aprox 15 min. As you said the toughest part of the whole fix is the red locking clip. I broke mine in the process of removing the old resistor. Once broken, I removed the resistor easily and used electrical tape to tape the connector to the resistor. Oh well, heater now works perfect. Thanks again
  • Thanks for the help..Replaced and everything working fine..This is the only place that I found that described what, where, and how to fix..You're right, the red clip was the hardest...lee

    I have a 2004 Jeep Liberty, and my drivers side taillight,tag light and front marker lights all stopped working,the turn signal and brake lights still work,anyone know what the problem is :sick:

    drivers side taillight,tag light and front marker lights all stopped working

    It would have to be either a fuse (fuses?), a broken connection or bad plug.

  • Im gonna go with a lose connector, happened to my buddies liberty and it was almost the same problem, had no high beam turnsignals and rear running lights however had brakes, after he tried to fix it himself and couldnt figure out how to replace the bulb i came over and figured it out. What had happend is the red safty clip had either broke or fallen out, and the connector came loose just enough to not make connection.
  • 2003 Jeep Liberty - The slower speeds on the fan don't work. Only the high speed works. Has anyone else had this problem?
  • I've had the speedometer stop working twice in my 2003 Liberty. Both times dealer fixed it under warranty. Now it's out of warranty. Do I have a hope of getting them to fix it again on their dime? Is this a persistent problem with Libertys? I'm also having trouble with the blower. Now it only works at high speed. Are the two related?
  • Yes, a few of us have. Please see message #1911. If your a do it your self, watch out for the red clip.

    :) I found out that the Liberty has a fuse that controls each side of the Jeep, I never t hought of checking the fuses since the passengers side worked, my baby is back to its old self..thanks.

    Just had the same problem with my 2003 liberty. Dealer fixed under warranty. The resistor needed replacement. Nothing is wrong with the fan switch. I believe the resistor is located behind the glove box. Empty out glove box, push in clips on each side, the box will swing down, giving access to the lower portion of the dash, wires, etc.
  • OK the dealer fixed the speed sensor for the third time on his dime claiming that now all 3 speed sensors have been changed. Are there 3 speed sensors or will there suddenly be 4 speed sensors when it is fixed the fourth time?
  • On my 2002 Liberty is one speed sensor, placed on the top of rear differential. I had 2x problem with it. Second time it was only broken wire direct on this sensor. Fixed it by myself.
  • Hey Guys (and Ladies), Here's a quick question - the headlights on my 06 Liberty stay on after I leave the vehicle for 60 seconds. I would rather they go off more quickly than that, say 30 seconds. I know other features are programmable, as I turned off that annoying horn chirp when locking the doors. Anyone know how to reprogram the headlights on interval? Any help would be appreciated.

    If you turn them off before you shut off the engine they will stay off. If you forget and shut off the engine first then turn them off- then on -then off---they stay off.
  • My wife had her Liberty at the service center yesterday and now the interior lights come on when she starts it and won't turn off any ideas :confuse:
  • faroutfarout Posts: 1,609
    93flhtcu: It just might be that the interior lite switch on the turn signal stalk is in the stay on position. It happened to our daughter's Jeep Liberty.

  • coatsmcoatsm Posts: 12

    Push the interior light (built in switch) in the back (by rear glass) four or five times quickly. Fixed my problem. As Farout stated, the Tech may have left it in the ON position, try one click first.

  • My wife and I have a 2002 Liberty and have noticed that the dash lights flash when the lights are on sporadically. Can any one answer this. The local Jeep Dealer is useless.
  • I have a 2002 Liberty - one of the first off the line. This weekend, I think I blew a fuse for the interior electrical. The radio/clock, lights, locks, and alarm do not work. I was driving when it happened, and it scared the heck out of me. Has this happened to anyone else? Thanks.
  • Have you gotten help with this? My sister's 2002 Liberty's lights momentarily flash off when she is driving with the lights on. It is instantaneous, but very dangerous and disturbing. We wondered if the problem was similar. The dealership has been unable to recreate the situation.
  • We just had our 2004 Jeep Liberty in to get the power steering pump and P/S hih pressue line replaced; when we got it back from dealer, the horn wasn't working? Any chance it was inadvertantly disconnected or forgotten when making repairs?
  • I bought my '02 Liberty Limited several months ago and have always been confused about the shifting console... Is there supposed to be a light in it, you know, so when its dark I can actually see the "R,N,D,1,2"? It has never lit up and my husband and I just think that seems unusual. Anyone? :confuse:
