Hey guys,
I noticed that the temperature control ***** on my wife's 2005 Suburban started to malfunction more than normal the other day. When adjusting the ***** for temperatrue control, the numbers jump all over the place. I have tried turning them slowly and the numbers go the opposite way or jump all over the place. Can these be pulled off and the contacts cleaned with alcohol, or does it sound like a module/control unit needs to be replaced?
Any advice would be much appreciated

 

Not sure where your located but..... I just purchased my new hoe and I noticed the same problem just last week. It only does it in my truck when it gets pretty cold, not sure if that could be possible where your at but. I noticed on warmer days it doesn't do it, also it doesn't do it after the inside of my truck warms up, let me know.
