One early morning on the way to work, I noticed all the dash lights weren't working as I turn on the headlights. After about 15 minutes of driving, the lights slowly came back on. The same goes for the next week where the lights will turn on slowly on its own after about 30 minutes of driving.
I did a search online and found this to be a common occurrence for the Mazda pickup trucks. The problem appeared to be a faulty dimmer switch. Since these trucks are over 20 years old, parts are not very easy to come by.
Using online instructions, I make a short wire with two blade connectors and inserted into the connector that was connected to the dimmer switch*. This process completely bypass the dimmer switch. The dash lights will stay at full illumination. It was a very simple 15 minute job to get it working again.
Remove the 4 screws holding the bezel to the instrument panel.
Remove bezel, disconnect the connector to dimmer switch.
Insert a short wire with two male blades into the two connectors that are parallel to each other.
Tuck it away and re-install the bezel.
Its that easy!
*Always remember to disconnect the battery's negative terminal before doing any electrical work.
