Over heating and found disconnected wires..PICTURES - Honda Prelude Forum

concLude · 07-17-2003, 10:03 AM

Ok, so ever since my JDM h22a swap i've been running VERY HOT. I recently put on the h23 ECT sensor so thats there and plugged in. I cant seem to get my fans to kick in for the life of me but i think i know why, key word think. A little while back i tried to get my AC running again and the mechanic said my compressor isn't kicking on and my fans dont blow. So i go snooping around and find two dissconnected wires.

this is the picture of the red wire that is connected to the compressor - obviously not attached but i cant find where to attach it to, any one know where or have a picture to where it is connected to?

here you can see the solid red compressor wire and a thinner red and blue spotted wire that is fryed up and dissconnected as well, anyone know what that wire is and where its connected to.

both these pictures are taken right behind the drivers headlight just for reference.

Brandon,

I can almost promise you that is your problem. I have couple wires that are from that area that go towards the fan.

So is it not hooked up period?

concLude · 07-17-2003, 03:36 PM

nope nothing, i'm almost thinking something burned up, so does zimmlude. I cant find anyplace to connect those wires for the life of me. I tried twisting them together and that didn't do anything.

you wouldn't happen to have a digital to take a picture of where those things go do you?

it also looks like that belt in the first pic needs to be replaced

concLude · 07-17-2003, 05:47 PM

sure does!!! that puppy started fraying the first test drive with the new engine, but has held for the past year.

Per our conversation on the phone:
I think that those wires should be connected.
In my car ('93 VTEC) There are three wires coming off of the top of the condensor. two red & one black. the red on the outside runs along the top of the starter, then down the face of it to a connector that is mounted on the fan gaurd. the wire off of that connector then runs over to the wire wrap that runs behind the windshield washer resevoir. The wire, running from the top of the condensor to the wire wrap looks to be about 12" in length & has a bunch of slack.
I think that the connector came undone & the section coming from the wire wrap got caught up in your belt as the slack looks like enough to allow it to reach that far. As it got caught in the belt, it damaged the belt (reason it is all ate up) and likely pulled/stretched it out & stripped off the insulation as it is shown in your pictures.
I'd reccommend having a shop look at it because that wire might be separated farther up and/or there might be other damage to the components involved.

**I have no clue if I used the proper terminology to describe the parts & if this is right. Hopefully that helped to work it out a bit.

Good luck man & let me know how it turns out.

concLude · 07-17-2003, 08:29 PM

yeah i'm thinking your right, it prolly pulled that wire enough to seperate it from where its connected further up in the wire.

Does any one have a picture of the connection where the power wire to the condensor goes?

the one thing that has me douting they are connected is just the fact that the gauges are different....but your prolly right mark

Dukespeed · 07-18-2003, 06:11 AM

Brandon,

Sorry bro I got home and my In laws were there.( BLah) No time to do anything. I will be able to get to the helms tonight if you haven't sorted this problem out. I am in agreement with what is stated above those wires need to be connected/thats your issue

concLude · 07-18-2003, 09:47 AM

i already tried tieing them together, and that didn't do anything.

yeah if you could still trace those wires that would be cool, i ran hot again today, this is gonna kill my car, if it hasn't already.

well the driver said fan is for the condenser whilel the pass side is for cool the raditor did you check your relay? did you try to put 12 volts right to the fan to see if the motor works? remember everyone KISS

[SUB[EX] · 07-18-2003, 06:15 PM

Hey, is that the wire from you AC condensor?? If that is the wire then you got some problems. That wire is a extremely LIVE wire so any grounded thing it touches will caus it to melt and short out whatever is connected to it. I forgot to connect mine and it almost cut all the way thru the bolt on the condensor, and i have also accidentally hit it a few times when working on the car and each time has causes a nice spark shower.

I wouldnt go blindly connecting wires toghter. Get a helms and trace all of those wires back until you find the problem. Im sure you most likely grounded it and melted the rubber off it then blew a fuse and stopped it from shorting.

concLude · 07-18-2003, 07:07 PM

yeah its the power i think, and i dont have any fuses blown. There are two red wires connected to the condensor, the wrecked one is the one furthest on the left, hmmmmmmm i'm thinkin about calling honda in on this one.... damn it.

but you guys are making it sound like this shouldn't be causing my over heating problem.

PreludeRacer023 · 07-18-2003, 07:40 PM

ok on my car i had that red and spotted wire loose, i found a little grey plug..it had a single blade in it, that the female connector could slide onto, not sure where the covering for it was though, but i hooked that up and my AC worked again, the other one i have no clue, your AC fan pro isnt coming on, but the main fan should..mine ran like that after my swap, temp guage all high ect..but it went away after a while...when mine was hot id shut it off, start it again and the guuage would read normal so i knew it was a glitch or something..peace

Dukespeed · 07-18-2003, 08:06 PM

OK sorry it looks as if they come from the a/c compressor clutch relay. There is a set of three plugs in the upper corner right behind the driverside light. Right in front to the right of the cruise control unit on the wall side of the fender. should be from the firewall out: A/C Diode,Condenser Fan Relay, A/C Compressor clutch relay. It gives a grouping of the wires that come out of them and the red blue is in both a/c and condensor relays. The red wire is only found in the a/c compressor clutch relay. Look at the bottom of these plugs and see if something looks odd. It looks as if the a/c comp relay and the condensor fan relay are hooked together and the A/C diode is hanging by itself. The picter I am looking at highlights the three little plugs in a circle diagram but I think they might be tucked a bit under the hood channel. Thats wher they are coming from. go look and tell me what you see in there. If anyone else wants to look its on page 23-115 of the helms. Peace bro. I hope this helps. Time for me to go get me a beer. peace.

i'm not over heating it seems when i turn on my heater, anyone have any idea why that would be the case? is my fan switch busted or something?

[SUB[EX] · 07-19-2003, 10:59 PM

ha, the heater will take the hot air from your engine and blow it in your car. That will always lower your engine temp. Thats a little trick you use when your overheating.

im still not sure why your overheating, its definately somthing with the wiring. If its that bad you can hook up a manual switch to use until you get the problem worked out. A few people on this board are using a manual switch because there fan was not kicking in. Its better then running hot and destroying your engine.
