Re: No Brake lights and fuses, relays are all good
As you probably have researched, the brake lights are fused with others but it might be worth checking anyhow.
Most brake lights are operated by either a pedal switch under the dashboard or a pressure switch located on the output side of the master cylinder; some vehicles have two separate switches in case of the failure of one.
It might be a good time to think about having an aftermarket manual for your car; they should be available from either or both, Haynes and Chilton. Having one lets you speculate on the reason for problems you are having in other areas and give you some protection against a lying mechanic.
(Yeah, they do exist.)

If your break lights are out, most likely it is not a bulb, because chances are slim that both would go out. And most likely it is not the connections where the break lights are because again, chances slim that both would go out same time. So, this brings us to fuse panel or the break relay. So, look in your owners manual it should tell you were your fuse panel is and what fuse is for the break lights. Most likely it would say break lights on the inside cover of the fuse box to tell you which fuse it is. Then if it is blown, you need to replace it with same amp fuse. I hope this helps, but I am pretty sure it is just a fuse. Thanks Mike
If all of your lights inside and out arent working, then its sounds like an electrical isuue. that cost as much as $1500 dollars. But i would start with checking the fuses in your relay box under the hood. That is usually where the lights fuse is at. Some cars have two fuse boxes and a relay box, one fuse box is inside the car, one is under the hood, and the relay box is under the hood. So i would check the relay box under the hood or fuse box if you can find one. granted your brother checked them all, it sounds to me like an obvious blown fuse... good luck
If the cooling fans are not working, there are a few quick things you can check.
Firstly if you have any electrical equipment you can check for power at the plug with a test light (you can buy one for 10 bucks) If there is power then it is the fan itself or the coolant temp sensors that are the problem. If there is no power then check the following;
Firstly all the connections and plugs etc, make sure they are plugged in correctly.
Secondly chech the fuse's, there should be a fuse for the cooling fans, it would be a good idea to replace it even if it does not appear broken as they sometimes break without showing.
Also the relay, you can test the relay by removing another relay that is working eg. headlights, and switching it with the fan relay to see if this helps. Just remember to switch it back.
If none of the above help then you may need to get the help of a mechanic that can test the curcuit and find out where there is a break.
