Hi, I'm new here so hello everyone. I recently bought a 2010 Tacoma Sport with only 27k miles on it. Am still getting used to it but so far I love the truck. I noticed the other morning on my way to work the fan speed and temperature control knobs have backlights but the heater/defrost/ac select knob does not. I cannot remember if it was lit when I bought the truck about a month ago or not but am assuming it was. My question is....how do I get access to the bulb to change it assuming it is a blown bulb?
