The temperature control nobs do not work properly. I have a 2004 Buick Rendezvous, and when I turn the control nobs to adjust the temperature the digital temp will go all over the place with no predictability. If I try to turn it up, the temp may go up or down. If I try to turn it down, the temp may go up or down. It takes a long time of fooling around with the controls to try to get the temp that I want. Is there anyway to fix this?

Try removing all of the HVAC fuses, make sure you get the memory fuse also, wait a few minutes and then put the fuses back in, that should reset the the HVAC system. If the problem persists then it time to take it to a specialist and have the system thoroughly tested, you may have a control module in early stage failure.


Thank you I will try this.
