Where is gas tank realese button in the trunk?

SOURCE: fuel filter on a 1996 Mazda Millenia

The fuel filter is accessable from inside the trunk. remove the trunk carpet mat. You will notice a circular panel on the left side which is held to the trunk floor with two screws. remove the screws and panel and you will immediately see the fuel filter. When replacing the fuel filter, note the direction of fuel flow and Do Not Install The New Fuel Filter Backwards!

SOURCE: mazda millenia problems

here are a few problems to look out for:

Check-engine light: Check engine light comes on due to carbon buildup on the exhaust valves of 2.5L engine. (1995-02)

Engine noise: Some engines make a metallic tapping noise requiring a new friction-gear spring on the camshaft. (1995)

Headlights: The headlight drain hoses can get kinked by the aiming screws causing fogging. (1995-96)

Keys: It may be hard to turn the ignition key because the steering shaft is not positioned correctly. (1995)

Steering problems: The steering wheel may be off center requiring adjustment of the tie rods. (1995). You can also have a look at the following website where some owner have given their opinions on owning one. http://www.carsurvey.org/reviews/mazda/millenia/r68654/comments/

hold light flashing means you have a transmission fault of some kind, check vehicle speed sensor

There is a small yellow rocker switch inside the glove box that locks a potential thief out of the trunk if he breaks into the cabin. Hit that switch in the other direction and it's fixed.

SOURCE: gas tank won't open, trunk won't open, radio stopped working, left tail lamp won't work

I have the same car with the same problems except for the tail light. My radio works when it wants. This morning I went out and my trunk was open and now it will not stay closed. I dont know what to do. I have no idea where to start with fixing the radio. Did you ever find a solution.
