sounds like you got something more serious then some bulbs....wouldn't think more than one bulb would go at a time in that cluster...sonoak said:Hey everyone. I have a 2006 Chevy Equinox LT. I have a few bulbs burned out in the instrument cluster behind the right side of the speedometer and behind the A/C Fan Speed Control Knob. Can anyone tell me what bulbs to buy for this repair? I have went to autozone and asked but was told "I dont know" I have also tried Sylvania's website, but didnt get anywhere with that either. My next step was going to be ripping the cluster out and taking one of the bulbs with me to autozone, but would like to get the bulbs and tear apart and repair right away. Any help you can give me is appreciated. Thank you.
