Wanderin Posted September 5, 2006 Share Posted September 5, 2006 Picked up my new MJ a couple of weeks ago and the heater, among other things, was inop. Checked fuse, it was good. Checked Fan speed control for power and had nothing. So somewhere between the two was a problem :mad: Ended up checking a few electrical connections before coming to the conclusion that it had to be inside that little box behind the control levers. Being Labor Day and everthing is closed i decided to tear it apart :wrench: Here are some pics...Some are fuzzy :wall: Before i got this far i noticed that the black box the electrical connector plugs into was split apart, so i might as well open it up :brows: nothin like 16yr old grease to gum things up. Keep track off them little springs :smart: Contact plate all cleaned up... Top half together again... Now that long square tube sticking up is real important :smart: It goes here, but the little lip has to catch the slider underneath or you won't be able to move the temp lever all the way to the left... Screwed together and zip tied...three of my locking tabs were broke :cry: I alson noticed that when i moved the slider completely to the left it would push that box up instead of moving that long arm up. So more zip ties were in order :D And here she is, all ready for reinstallation :banana: Got it all back in and turned the key on and it was working fine in all fan positions. Went to change off defrost and nothin :cry: Then it dawned on me to start the truck for some vacuum :dunce: She works like a charm now. Hope someone gets some use, or maybe a good chuckle outta it :P Link to comment Share on other sites More sharing options...

Oizarod115 Posted September 6, 2006 Share Posted September 6, 2006 i couldnt figure out why my blower for the heat stopped workin for nearly a month in the dead of winter. (GA winter but still.. I'm easily cold :brows: ) never dawned on me to check the fuses...NUR NA NURRR. PO had the wrong size fuses in EVERY spot. 15s instead of 25s and such. so alot of them were blown. and i figured out what the funky lookin thing in my dash compartment was! the hazards relay... :D :D good to know that it is easy to fix if things actually do stop working by their own faults. gracias. (cw is right.. this is alot like the broken hood cable thread. lifesaver if you know it beforehand) Link to comment Share on other sites More sharing options...
Wanderin Posted September 7, 2006 Author Share Posted September 7, 2006 Seems the only posts i could find on the subject was to replace the control box, so i figured i had nothin to lose by tearing it apart. I know some people might consider it a waste of time, but i thought there might be others who would like it, thx. Link to comment Share on other sites More sharing options...
Hot Rod Jeep Posted September 7, 2006 Share Posted September 7, 2006 A waste of time? Us poor people have to do with what we have. I don't mind tearing something apart and cleaning it instead of buying new, saves money that way. 8) Link to comment Share on other sites More sharing options...
