I've made a huge mistake. I've had my Discovery for a couple weeks and have been having fun working on it. I wanted to get my radio and cigarette lighter to work so I did some Googling and found that it might be a relay. I don't know what that means but I saw pictures. I opened the panel on the passenger side. I saw 3 relays...



I wiggled the back one to see if it would come out. I saw a spark and realized I'm in over my head and quit messing with it. Now when I turn on the truck the a/c doesn't blow at all. Does one of these control that or have I messed up even more on my truck? It's summer here in Texas so where can I buy one of these locally so I don't have to wait on it? What would I ask for at the auto parts store?

After this I think I will leave the electrical stuff to the professionals.

 

Seeing a spark is usually like seeing a small lightning bolt, and you have most likely just blown a fuse. Check each one under hood and the ones under the dash. You can buy fuses at auto stores and Wal AMart.

 

if you think you need a relay, usually you can just pullit out and a good auto parts guy can cross-reference one for you....a really good store can check the relay
