  1. XJ Cherokee Technical Forum
    I have a 2001 Cherokee, 4.0l and I'm having an issue with not blowing cold air. This started almost immediately after I replaced the blower, so there's a possibility I damaged something in the process. Symptoms: -Lukewarm air blows on Max A/C -Lukewarm air blows on regular A/C -Compressor kicks...
  2. WK2 Grand Cherokee Forum
    My wife's Jeep (2013 Overland Summit) has been experiencing an intermittent blower fan operation for the past couple of weeks. I attributed this to the blower motor resistor because we had an older Jeep with exact symptom and fix in the past. Yesterday I installed the replacement part however...

    Hello all! I have had a problem with my heater blower motor that's a little odd... so the blower only works every once in a while, and continues to work until I forget to turn it off before I turn the jeep off, otherwise it does't work for a week or so, the decides to turn on. all of the other...
  4. TJ Wrangler Technical Forum
    Hey guys, So I bought an old 99 TJ off a friend a few months ago. Decided to tackle a problem with the blower not turning off. Pretty much the whole hvac cluster doesnt respond, other than the temp control. Cant turn it off, just blows on high constantly. PO said he was "having problems" and...

    When I bought my Jeep the AC worked awesome. The blower motor blew a fuse recently (Original fuse) I replaced the fuse and it worked great. Then Start it up, turn on the AC and nothing. Checked the fuse and it was fine. Checked the fuse under the hood and it was fine. So here is the Bizzare...

    I have a 2005 TJ that for some reason it will only blow air out the defrost vent below the windshield. It will not blow out the front, along the doors, or at the floor. I replaced the A/C Heater Control Module. (This is a picture I stole off ebay, but it just shows what I replaced. This isnt my...

    There is a moderately severe ticking noise when my vent blower is on at any speed. I would love to get rid of it. Any help is greatly appreciated!!
  8. ZJ Grand Cherokee Forum
    Hello ... The heat in my wife's ZJ will blow onto the floor and through the defrost vents but not out the dash vents. You can feel heat coming out of them, it's just not blowing as it should be. Her ZJ has manual AC controls. I did a search and looked at the vacuum lines that were under the...
  9. KJ Liberty Forum
    2007 4x4 Liberty (used, condition/maintenance prior to ownership is unknown) My heater stopped blowing on all fan speeds a couple days ago. I changed the resistor Tuesday evening. (Today is Thursday) All seemed to be working normally after the change that Tues night, and into most of the day...
  10. YJ Wrangler Technical Forum
    When I turn on the heat, it only blows hot air when I'm driving. If I'm not moving I don't feel heat coming out of the vents, so I know the heater core is fine. How can determine it is the blower motor or a resistor? I don't know much about this so any input would be great. If anyone knows of...
  11. KJ Liberty Forum
    Ok, so I just got my 2006 Jeep Liberty 4wd about two weeks ago, and I noticed the other day that the A/C and heater only blow on setting #4 (high). I've done a little bit of research and a few things have been suggested. First of all, the blower motor resistor. And secondly, the blower motor...
  12. WK Grand Cherokee & XK Commander Forum
    2005 grand cherokee leredo Heat only blows through defrost and floor. I have checked everywhere for a vacuum leak with no luck. Even sprayed starting fluid on just about every vacuum line I knew of with no changes to motor while running. Fan speed only works on high a lot of the time. As I...

    2008 Wrangler blower motor doesn't work at all. Used the day before, heat blasting, no issue. Also, the hazard lights do not work when the jeep is running but work when it is off. Was going to try the blower resistor but will be a couple of days before I get it. I already replaced the blower...
  14. TJ Wrangler Technical Forum
    Hi all. I have a 99 sahara V6 that I've had for about a month and there are some really strange things going on and I wonder if it could all be related or if I'm in for a lot of different repairs. 1. The right turn signal only blinks when I give the engine a little gas. When braking or sitting...
  15. TJ Wrangler Technical Forum
    So I only had one fan speed on the AC working and decided to replace the resistor. All speeds work now, but my headunit no longer works, and when you turn the key back (as opposed to forward to turn it on) none of the auxiliary electronics work (stereo, dome light, etc). Any ideas? Is there a...
  16. XJ Cherokee Technical Forum
    Greetings Jeep enthusiasts, Synopsis: What can cause an air conditioner that has worked for years to suddenly cool at slightly less than outside temperature but not at 58 degrees or whatever the ideal target is? I have a lifted 2000 Cherokee Sport and I love it. It is my second Cherokee Sport...
  17. WK Grand Cherokee & XK Commander Forum
    Hello everyone, I have an 05 WK and just recently all of a sudden the Heater/AC completely stop working. I have no fan on any speeds or settings. I have checked all fuses and relays and also replaced the blower resistor. Any thoughts on what it may be? Your input is very much appreciated...
  18. TJ Wrangler Technical Forum
    My blower is not working at all. I replaced the switch in the dash and the blower itself but still nothing. It is not working on any speed so that tells me it's not the resister. The fuses all look good. Could it be the relay? Or is there something else I need to look at? Thanks!
  19. TJ Wrangler Technical Forum
    My blower on my heating and A/C is not working. When I am driving air will barely come out but other than that nothing. A few months ago it only ran on high, and now if I hit a hard bump the high setting will sometimes kick back in. I'm pretty sure that it is either the blower motor resistor...
