I have a 98 prelude stock aside from aem intake. I picked the car up a few months ago with 168000 miles for $1700. It had no title and the cel was on. It needed a new Cat, spark plugs and throttle position sensor got it somged and the DMV issued me a new title. Everything was good until the other day. My right blinker starts blinking fast. I figured it was the bulb so I replaced it and it still didn't work. I figured it was a wiring issue and was going to take care of it this weekend that day on my way to work when breaking to get off the freeway the horn started buzzing like I was taping the button really fast then stopes as soon as the car stopped. Then today it was a little warmer and there was traffic and the car started overheating. As soon at I started moving the temp would drop. Pulled over and the temp started riseing. Checked the fan and it's not comming on. Anyone know if these share a ground or power supply. Any help would be appreciated.

 

your going to have to check the helms manual..
I just checked about a month ago, in regards to the radiator fan.. but for the life of me, i cant remember what i did to check.. lol

I know that the horn, and the cruise control share power..
as far as the turn signal, it might be the relay..

 

Now I'm having more problems. The battery light keep coming on and then it died while I was driving on the freeway in the rain. I don't know if it was the power or the ground to the altornater but the one that is bolted down with a 10mm nut that wires connection broke. With all the other wiring issues I'm having would it be easyer to just replace the wiring harness or trace down the problems and fix the one I have.

 

Replacing the engine harness or chassis harness? it'll be hard for me to guess where your problem is, so I would vote to troubleshoot your current one. Obviously, you have to start fixing with the alternator.

Who knows, maybe that connection was already breaking the other day and causing other side effects? But more realistically, I would fix/check the alternator, then check the horn wiring bc I bet it is simpler than the turn signal. If you are missing the Ground or the POS+ 12v signal to the horn, then track back up the wiring until you find an issue on that wire source.

For the turn signal: did you check all bulbs on that side? If all are working except for ONE, then check the wiring at that position to see if it is receiving a Ground and/or POS+ 12v signals. If NONE are working on that side, but the other side works, then try to swap the relay for that side with the relay for the other side. Did the non-working side switch sides?

I found the problem yesterday. On my way home from work I heard a rubbing noise comming from the passenger wheel well. When I got home I started to investigate and found the the wiring harness that is under the wheel well cover (witch I don't have) was hanging just low enough that when I hit a bump the tire rubs it. Im guessing it's been doing this for a while because from what I could see at lease 4 wires have been rubbed so much that they broke. Im going to have to pull the tire off the get in there and then it should be easy enough. Just solder in some new wires and figure a better way to hole the wires up then tape until I can get a wheel well cover or whatever that thing is called.
