Turn climate **** all the way to right, fan **** all the way to right, setting **** to left. Hold the climate button and control button down until they stop blinking.

We all have the same issue as you do. This reset did not fix my issue. Let me know if you find a fix. Thanks

 

Phase did you replace the temp. Control that Humbie posted with the service bulletin? Or did you just change out the blower motor resistor?

 

Im back but im so busy at the moment I will post when I get this fix, I saw tha part replacement I think im goin to order after I check mi resistor and connector I really think is goin to be the controls.

 

This makes me thinks its a computer issue. We all have the problem after power was disconnected. I checked my actuators today and they seem to be working. This problem has happened to me before, then fixed itself. So it doesn't seem to be an issue of something "breaking". I see this issue all over the internet, but no fix. ugh

 

I tried the reset several times but my led lights never would stop blinking. I assume there is something else going on that does not allow for the reset to happen. I did read though that the reset is used primarily when the whole control panel is replaced. Still researching about the 60 to 68 ohm inline resistor to bring back the reference voltage into range. I am doubting anyone should do this as it doesn't make any sense as the voltage to the swith is only 5 volts. Unless a circuit in the control panel has malfunctioned then I not sure adding a resistance would be the best plan. Kind of the same thinking on the fix for the burnt fan connector, it really doesn't explain why is it getting hot and expanding the spad connector inside the socket. No I didn't replace the temp control or any of the control module. If anyone has any more info please post. Thanks to all, seems to be a unsolved common problem on both of these issues.

 

*****i promise i will post when i get this fix, and is fix. the problem is controlers for sure i order the controlers and replace those myself so im 100% sure thats the problem the ones i have in my hummer are made in portugal and the ones i replace are made in mexico just for reference they have different part number good luck to every one fixing yours .

 

That's good news. Let us know if it stays working. Did you diconnect battery when installing? I've heard of stories people buying new control units then problem reoccurring a month later. Hopefully this works!

 

I remember the fix from a few years ago but the info is gone now, and I had a truck this morning with the same issue. I actually found the fix on a forum for 06 pontiac solstice. The light blue with black stipe wire, terminal f circuit 1688, on the driver side of the hvac control head needs a 60 to 68 ohm 1/2 watt resistor installed inline. it does something with keeping the voltages in spec. The new part #25920831 is suppose to also take care of this, older part # control heads such as 25814719 will not. Good luck, jason.

 

No I didnt disconnect battery, and yes I hope stays working, if not ill post.

 

I've heard of the resistor problem for the AC blower, but not for the temperature control issue. Is this a resistor that can be added for the temperature control rather than buying a new control unit?

Thanks for your help!
