The carpeted piece(s) is held on with two fairly large bolts (1/2", if I recall correctly) and some miscellaneous screws. The dash plastic curves inward at the top and "captures" it, so you have to...

The interior lights are controlled by the courtesy light delay module. It is fairly common for the transistor that turns on the lights to short out (then they stay on all the time). It can also burn...

The '86 model has several unique wiring changes. For one thing, the fog lights do NOT ground through the headlight filaments. They have an independent ground. That makes it much easier to do a HID or...

The old O-ring is still in the pump. You need to get it out before you can seat the new filter correctly.

Some time in the '90s (I don't know what year), the SECURITY light function was changed to indicate VATS status. I assume the TDS and VATS functions were combined.
