I need help, I can not find any information online regarding this problem. I have a 2005 Camry XLE, my climate control worked when I purchased the car about 2 months ago, and then it sporadically went off and the LCD screen icons disappeared. The backlight works for the buttons, but the buttons do not work. The LCD backlight does not work. I tried replacing the electrical relay for it, and also tried replacing the entire assembly, the problem continues. However, the other day I was driving home at night, and I realized that when I changed tracks on my CD player, the backlight quickly came on and shut off for the climate control's LCD screen. Note, this does not happen every time I switch CD tracks, but it happens once in a great problem. I do not know much about this stuff, what do you think the problem is? Thank you in advance for your help.
