Intro and a ZILLION Qs

[yaisami]

Hello all,

My name is Sami (yai is big in thai), this is my first post, but i really do wish i joined a long time ago. You guys know what you're talking about, and the only thing I know about cars is asking the dealer how much will this cost me. I'm hoping with your help, I can do some things on my own.

We have the 2002 4.4 full sport package and 20s, silver.

I know I'm new, but I hope someone will answer my Really stupid questions.

The navigation system is completely dead, we spilled water in the back, and i think that was the reason. The dealer said they have to change the computer (or something), for a cost of $1,200. I thought I'll check with you guys first. Save money and make new friends, what could be better than that.

Q: if i reset the computer by unpluging the battery for 15 minutes, will this harm the car in any way.

Q: I wanna check all the fuses, can i just take them out, check'em then put'em back in with no problems. Or do I have to disconnet the battery first.

Many more to come.

thanks, and i think i'm gonna like it here.
