rowingsunny Posted January 28, 2009 Report Share Posted January 28, 2009 (edited) Hello Everyone, I have an 05 Jimmy and my differential lock up computer is shot on the stupid thing. It is a little computer that is located on the passenger side just in front of the door and it engages the 4x4. For me to order a new one from GM I am looking at $1000. I am trying to locate a used one but with no luck as of yet. Since mine is the last year they were in production it has to be certain part number. That part # is 12577412. I have tried all the wreckers in the niagara region, do you guys know of other wreckers I could try or maybe another solution. Much appreciated, Sunny Edited January 28, 2009 by rowingsunny Link to comment Share on other sites More sharing options...
marty5898 Posted January 28, 2009 Report Share Posted January 28, 2009 Have you considered ebay? Ebay link Link to comment Share on other sites More sharing options...
ecmilley Posted January 28, 2009 Report Share Posted January 28, 2009 how do you know it's the transfer case control module? the most common issue is the front diff actuator goes bad and thats a $135 fix plus labour Link to comment Share on other sites More sharing options...
rowingsunny Posted January 28, 2009 Author Report Share Posted January 28, 2009 I brought my truck into a mechanic and he diagnosed the problem for me. They initially thought it was just a cable that initiates the front tires and it would have been a $100 repair but when he looked into it further he found out it was the transfer case module. Which is apparently a common problem. I just went onto ebay and was able to find brand new one from the states for $244.00 CDN, that is cheaper than what the wreckers were charging $250 CDN but they didn't have the correct product number. So thank you very much marty5898 your suggestion helped a whole lot!! Now I will have 4X4 once again!! Cheers, Sunny Link to comment Share on other sites More sharing options...
