When sitting in the drivers seat, it is in front of your left shin...pull the cover off where it says fuses and look at the diagram on the back of the cover. match up the one on the drawing with the one on the fuse box.

You can get to the fuel pump by pulling up the seat cushion on the rear seat. There is access to the fuel pump there. You simply twist off the locking mechanism, pull out the old pump, and drop in a new one. It took me about 10 minutes to do mine.

The brake light is controlled by a little button switch that's mounted high on the brake pedal lever. If you follow the brake pedal upwards with your fingers, you'll feel the button.

It has a spring in the button that pushes the button back out when you release the brake pedal. If the spring jams, the brake lights stay on.

Replace the button switch.

MOST GENERALLY, OVERHEATING OF TRANNY IS CAUSED BY THE TRANY OIL COOLER UNIT LEAKING, OR PARTIALLY PLUGGED OR THE FINS FILLED WITH DIRT AND ROAD GRIME. Inspect and clean. IF THE TRANNY LINE IS LEAKING, IT WILL BEGIN TO GET TOO HOT and overheat. SOON IT WILL BEGIN TO BE TOO LOW ON OIL TO DRIVE THE CAR. You can run into this problem at any time. Getting low on oil will cause the tranny to stop working. It will start slipping and then stop working. Naturally, it will cause it to overheat.

This will happen ESPECIALLY IF IT IS A HOT DAY AND IF YOU ARE PUSHING THE VEHICLE HARD. So, check out what is going on.

If you are on the road and it stops pulling, you may have to get down under the front of the vehicle and see if it is wet on the ground and on the car with tranny oil. Most tranny oil is red sometimes it is grey. (caution: Do not use motor oil to replace missing oil in the tranny. This will permanently ruin your tranny.) If the tranny is leaking it will show wet with oil on the ground and on the vehicle. Go and get the right oil from a nearby service station and add three or four quarts, enough to get the car to drive to the nearby station and then go from there. If it is a copper line leak, clean it. Then get some flux and a hot iron and solder. Solder the hole and refill the tranny. Check for leaks. This should work. If it is a rubber hose, clamped on, replace it.
