  • gm did a recall on this. i put the link on my website cause gm makes it almost impossible to find.

    http://webonlinefor199.com/gm%20recall.html
  • I keep trying this link but am unable to get access. I have a 06 2500 HD the dealer replaced the part once then I had it replaced a second time at a cost of $400. plus.
  • The link is back on line. I create websites and had a demo site on line. Have a great day
  • Link is back online.
  • Great post and glad to see that recall. I DL'd the .pdf and posted it up on Diesel Place.com. There might be a few of the 125,000 truck guys there that might find that interesting.

    Heres one for all. 2006 Sierra 2500 HD: in 'winter - Drivers side blows cold air - Pass side is normal at whatever temp setting is. Is this my mode actuator or a blend door actuator issue...or could it actually be the reflash that my truck might or might not have gotten.? Build date is Oct 05.

    To date I have simply (in winter time only), disconnected the batts for 5 min or so, turn key on and let system calibrate..worked all last year but a PITA when its -40 out.

    thanx
  • My 2000 Silverado 1500 Climate Speed Control does not work on the first 3 speeds. It does work on speeds 4 and 5. Where or how do I trouble shoot the problem?

    You could buy one off of ebay.

    a/c controller

    Or remove yours and replace the diodes on the speed switch.

    Been a long time since I posted here but I still have my 2000 Silverado 2500 2wd excab shortbed.
    Here is the scenario: Parked truck for couple of days. Last night could not unlock door with key fob, OK use the key. No dome light, no start, no nothing evrything was dead.
    Hooked up battery charger, as soon as I powered up charger dome light came on and the defrost is running fullspeed with fan control set for "off", temp setting on midrange and source setting on "floor".
    I have no clue what happened or caused this.
    Any suggestions/help appreciated.

    I recently bought an 06 gmc sle and have been having trouble with the dual climate control. When I have the ac on or even just have the fan blowing with the temperature setting on cool. The driver side will start blowing very hot air and the passenger side vents are normal. When I turn the truck off and start it back up, it is fine for bit, and then it will do it again.
    Anyone have any ideas?

    No matter what setting, the driver's side would creep up and become hot.

    I tried every fix found on the internet and ended up going to the dealer who replaced the driver's side blend door actuator at the cost of about $400.

    It was fixed in late June and I haven't had a problem with it since.

    Good luck.

    UPDATE:

    Replaced the resister on fan motor housing and resolved the problem.
    $26 part at AutoZone in stock.

  • I received the letter but have lost it. I think I am nearing the mileage cutoff for the repair. Can you send me the link or the pdf so I can print it up and set up an appt!! It is impossible to find anywhere else on the internet....
  • I can't get my heater to blow out hot air. In the past month I've changed the heater core, the thermostat and water pump due to separate issues but I still can't get it to blow out hot air from the vents. It does blow out cold air though. I also hear what sounds like bubbling/boiling water in the cab when I'm driving (stepping on the gas only). I really need to get this fixed before the really cold weather hits. What can I do???

    Sionce the heater system uses coolant to heat the air the most common cause of no heat is low coolant. When changing the thermostat, heater core, and water pump, the system needs to be topped off after the thermostat opens. If not you'll have low coolant.

    Have 2006 GMC 1500 doing same thing. One thru four works but # 5 does not. Received letter from GM last week (special Bullentin 10240) on manual temp control switch. Gm realizes theres a problem with the hvac system not working on certain blower settings and would repair this problem if taken to GMC dealership. Took my GMC to Macon Ga. dealership and was told #5 was not in the covered plan to repair. Dealership said it would cost 328.00 dollars to repair. Can anyone figure this out?
  • I'm glad that you posted, Redge.

    We would like to speak with the dealership to clarify a few things. Do you have an appointment already set up to have the repair done, or is your vehicle currently in at the dealership for repair? Please send us more information, including your name and contact information, the last 8 digits of your VIN and current mileage on your vehicle, and involved dealership. With this information, we will set up a case for you with Customer Assistance and will be following up for you with the dealership.

    Thank you in advance,

  • Did you ever get this fixed and what was the solution? I have a chevy tahoe 2004 and I have had this exact same problem for a couple of years now. Thanks
  • Yes I did, after replacing 2 of the fan control modules I replaced the wiring harness at the fan. The stock harness overheats and melts, shorting out the contacts, bad design. Not hard to change, just have to pay attention, the replacement harness wiring isn't color coded. Can't remember if I bought the new harness on Rock Auto or off of ebay, but it was like $17.00. Good luck and Merry Christmas!
  • I have an 2006 1500, last week hot air stopped blowing out of the driver side vents and continues to work on the passenger side. It has sporatically come back a time or two but is gone again after the truck sits for a couple hours. Any Ideas whats wrong or how to fix it?
