I just got schooled on this very topic. If the fuses are good, it may be the light timer thats taped to the harness up by the heater-core area.

Make sure it's not the fuse before you go hunting for the timer, but if it is the timer, you bypass it by splicing together the three white wires.

AGENT86 gave me this info the other day. My lights and trunk went out and were out for a month, then they just started working all of a sudden. Could just be a loose wire at the timer if it's not the fuse.

Clock/Courtesy fuse. On the fuse panel, it is written CLK/CTSY.

CLK/CTSY also fuses the cigarette lighter and the electronic A/C controller. The courtesy light module also allows the rear hatch to be opened by the door switches (but only when a door is open).

15A (blue - azul to you ;-). Since I just replaced one, I know it's in the top row in the fuse panel.

My interior lights also did not come on and the hatch would not open when I first bought my 92. The problem that I had was that the door ajar switches were bad in both doors. Replaced them and lights and hatch work fine.

Check your FSM for the method to remove the switch. On the 92 there is a backer plate that will fall off if you remove both screws.

ok I found the problem. more like AGANT86 found the problem. yes it was a burn fuse.

I change the fuse and all the light turn on.

but now the lights on the roof pilar. they stay on for ever.

the door cortesy light will turn off after a minute or so. but the other lights stay on.

I dont have a light under the dash yet. I have to install those.

but why the 2 pilar lights stays on all the time????? any idea

The cargo lights are also controlled by the switch at hatch latch. Have a look at the switch and the pin the contacts it.
