How to Replace Dash Lights in a Toyota Corolla

Removal

• 1). Disconnect the Corolla's negative battery cable. Wait at least 10 minutes for the air bag's power to be depleted. This is an important safety precaution to avoid accidental airbag deployment.
  
  
• 2). Loosen the screws on the side of the steering wheel with a Torx screwdriver until the threads catch on the screw case, then lift the air bag off the steering wheel and disconnect its electrical connector.
  
  
• 3). Mark the steering wheel's relationship to the shaft with paint or a marker, then remove the wheel's central nut with a wrench and pull off the wheel -- this may require a special puller tool.
  
  
• 4). Pull out the single pin on the underside of the cluster trim bezel, then pry off the bezel with a screwdriver to remove it.
  
  
• 5). Remove the single screw at the top of the cluster, pry and release the two bottom clips and pull the cluster out. Disconnect the electrical connectors in the back.
  
  
• 6). Turn the bulb holder for the light(s), located in the rear of the cluster, counterclockwise and remove them from the cluster, then pull the bulb out of the holder.
  
  

Installation

• 1). Push the new bulb into the holder, using gloves or a clean rag so oils won't get on the glass. Insert the holder back into the cluster and turn it clockwise.
  
  
• 2). Insert the cluster back into the dash with its clips and screw.
  
  
• 3). Reconnect the trim bezel onto the dash with its clips and the push-pin on the underside.
  
  
• 4). Reconnect the steering wheel to the shaft, lining up the markings and tightening the central nut. Reconnect the air bag to the wheel using the Torx screws.
  
  
• 5). Reconnect the battery cable.
