How do you change the instrument panel light of a Toyota Corolla 92?

You have to remove the instrument cluster to get to the bulb. start by removing the left speaker grill, lower left trim panel (5 screws), remove the steering column trim cover (6 screws), remove the cluster and trim bezels (9 screws), Remove the cluster by pulling it out ( 4 screws).

This is right. Just to add.

1. remove the cover that is above the steering column. THis cover is the one extending from the left side of the driver going to the center panel covering the aircon switches down to the DINs. There are just 4 screws for that.

2. remove that cluster bessel. this bessel is the one covering the cluster gauge to the clock and the stereo (head unit). After removing, you will see the bare clurster gauge.

3. unscrew the cluster gauge, there are 4 screws there i think. just search around it, it is easy to find actually.

4. pull the cluster gauge. for XL Corolla 92, there are 3 wiring sets connected at the back. Just unplug it. (it is like and ethernet cable that is used between your desktop and modem that needs to be pressed to release).

5. Here's the hardest part. removing the speedometer's cable. that's the biggest/thickest cable you can touch behind the gauge. It is hard to see it due to limited space. Find a way to reach that thick round cable, press hard then pull. Again, it is like a round ethernet cable that needs to be pressed to release it from the connection.

6. Once done, just get the cluster gauge and look at the back of it. just twist each black knob to remove it. inside each knob, you'll find your bulbs.

One suggestion, just replace it with LED bulbs. I think there are 4 bulbs for gauge's background lighting and for the rest of the bulbs are for the gauge icons (left signal light, right, door ajar icon, handbrake icon and etc.). just peep through each hole where the bulbs are plugged in to identify what bulb is for the background light and for icons.

LED bulbs in the Philippines: 150 pesos for 2 pcs (43 pesos = 1 US dollar) while the regular bulb like the one you'll find in your dash is just 10 pesos (43 pesos = 1 US dollar). Dirt cheap. :)

Hope this helps.
