Alright. Before my old motor dropped a valve seat the car would get hot. I noticed the fan did work some times but then it just quit all together and now after getting it back up and running I want to fix that issue before the car over heats and potently causes a valve seat to fail.
Here is my thread over on FEOA.net, I wanted to post here to kinda get different answers to things. The current post in my thread on there is what’s been happening recently.

I did the relay mod that’s on there to use standard relays, I’ve checked and triple checked the wiring on those relays. I get power to the relays like stated in that thread but it’s not sending power out from the relays to the fan. The fan indeed works because I wired it right to the battery. Both high and low work.
Thanks

I actually may have had a blonde moment(I’m not blonde though lol) and was testing the relay backwards. MAYBE. I don’t know. I got a video for you guys. Don’t know if it helps or just makes me look like a fool.
Video is uploading now.

And its the opposite if I key on fuse out. While probing with the positive probe. Just no power at the fan wiring.
BK/WH is 86.
R/BK is 85.
These top two as listed are your coil. One should have a hot. The other side would be triggered by a ground from pcm.
LG/BK is 30. This one would have the Battery positive and or the heavy load.( Now after saying that, a ground could be used for what ever)
LG is 87a I clearly do not think that should be hooked up in this application for it would be hot all the time.
LG/Y is 87 this one should be hooked to your fan.The bottom relay should be the same. I really question why the X is on the one tab 87, because from what I see it should be on the one below it. (87a will be hot through 30 all the time when the coil is not energized)
Take the relay out, hook a 9 volt battery across 85 and 86. It will not make a difference of positive or neg to either one, it will not care. You should feel that coil when energized switch contact between 30 to 87a then to 30 to 87. (continuity)The starter cut off relay you speak of is that listed as cooling fan power relay? On that diagram I listed. It’s hard to do anything today because we got ice rain last night and there is a layer of ice everywhere. I don’t have a garage so I do everything in my driveway lol.
I will let dreamer respond to that for I have not looked at your wiring diagram as of yet.
Are you sure you have the right relays?O.K. just had a few minutes to kill. I see the Hi speed fan relay does feed to your Low speed relay when Hi speed relay is not energized. So disregard my thought on the relay that uses 87a and 87. 87A is feed to your low speed relay.
Issue is fixed. I kept thinking and thinking about the relay in the fuse box. I said screw it I’ll buy a new one. Sure enough I replaced it and the fan fires right up when I do the ECT trick and key on fuse out. Thanks for your help guys!

Which relay? The starter cut off relay that i suggested checking earlier?
And I’m really glad the issue is fixed. I had started to edit that wiring diagram and was about to link here here showing where and how to test.
Please after you let us know which relay was bad, that you change the traffic light to green so it will update our database.C8-)
Its the relay in the fuse box under the hood. Can’t recall what it’s labled as. I believe that one does control the starter too.

I’ll get a picture of it here in a few. I’m just relaxing now lol.Quoted From dreamer2355:
Interesting. Ill have to check out some more wiring diagrams to see how that relay is used.
Yes.
I am wondering if that was the right schematic since the video showed he had 4 out of 5 wires (and should have been suspected) showing 12 volt potential. That would have showed the starter relay was giving 12 volts to the other two relays.Quoted From rebel4055:
The diagram was from ondemand. So must be right.
I’m not a big fan of Mitchell’s wiring diagrams. They redraw the factory ones so they are uniform, and to be honest, I can’t stand ’em. I’ll take alldata or OEM sites all day.
