Like many I performed the fan override on my 97 SSEi, only down side I noticed was the CEL would come on if I forgot to turn off the switch, turned off the car and restarted. The PCM checks the circuit and sees the grounding.

I thought about how to work around this problem of my forgetfulness.

Talking to friends I came up with a couple different possibilities.

1. Cut the wire from PCM to fan and put a diode inline. I'm not a fan of cutting factory wires.
2. Use a single relay, wiring to include a self latching and hooking the power to ignition. It would reset automatically when the car is turned off. Downside is you can't turn it off w/o turning the car off.
3. Using a momentary switch to turn the fans off and on. One push = on another push = off. There are two ways to follow this path, both involve a latching/unlatching circuit.

I chose #3, I want the ability to furn them off as well as on.

Gathered 6 relays and wired them per a website (I'll add link later) to put out a ground. Could have used 5 if I added two diodes, had plenty of relays sitting around after a junkyard trip. I have this together and it works great. I have an idea that I need to research further that would turn on a dash/cluster light when the fans were on.

I am going to build a circuit per another website that uses integrated circuitry to do the same. The only down side I see to this is electronics have a higher failure rate than relays. It'* not a high number though. Still need to gather the parts for this project.

I will be getting pics and links up soon, also want to gauge interest.

well the CEL problem will be solved....Im wating to see the placement of the Button and the "light"

there are plenty of spots in the factory gauge cluster to put a new "light" if all else fails use the "rear steer" light.

It seems to be the only spot w/o having to molest the face. I discussed this w/Pat yesterday since he'* got a few clusters and faces laying around now. I may have to cut board traces that would power the light normally and tack a connector on, however it is very workable.

it would be a good joke item also.

Here is the relay pack I made. It'* 6 in total and I've bench tested it. Works good.

I found a momentary switch, removed it from it'* previous home and added it into the seat switchpod. (Note: PACSWI hole right behind it)


Tomorrow the button and rest of switch pod will be painted the proper color.

I'm still tracking down the correct chip to make a IC version.

GO Boosty go!

Kinda crowding that corner of the seat switch trim, no? Why not in the center?

Because when my cupholder is out it has a support in the center. ps.. I need to paint something tomorrow...lol

Ahhh. Good thinking. I would have just been swearing my butt off when the drink holder was clickin my switch.

Morning is better for me. Margaritas for breakfast?
