What have I missed?
Suspect that my '96 993 is running a little warm now that things are heating up in Southern California.
Reviewed extensively Randall’s site and info.
Unable to gain any oil cooler fan operation by ‘jumpering’3 & 7 or 3 & 5. Resistance between 5 & 7 is 4.5. Similar results with the AC Fan.
Am I missing something with these diagnostic procedures?
With thanks,
Jordan

Hey Jordan,
I have been told that adding the TURBO S ducts in place of the foglight help to improve oil cooler and air conditioner temperature. Since the ducts are not run to the brake discs, they ram air onto the oil cooler and A/C unit.
It's just a thought of something you might want to try if high temps is bothering you both with oil and A/C..

Jordan,
Can you define “warm?” While your temp gauge will be higher in warmer weather, it doesn’t necessarily indicate a problem. Having the needle at 9:00 or even a bit higher is not a problem.

Yeah, that’s warm, but it’s not hot. It’s not unusual to see that on a hot day in stop and go traffic. It’s nothing to worry about. Pulling the fan plug ala E.J. should help, but then you’d run too cold at speed (it’s important to get that oil up to temp). Ideally, the fan would be smarter, or you could wire a switch like some others have.

Jordan,
Randall IS your man on this issue, IMO. If all is working properly, you might also want to consider a switch that manually turns on the high-speed fan when you're in traffic. FWIW, your temps don't seem atypical. I had similar to you: gauge about 9:30 in warm weather + traffic, but down to 8:00 at steady speeds. Since I track the car and also wanted the oil to run cooler in stop-and-go, I put in a switch and am happy with the results and the convenience it provides. Just a thought.

Thanks for you suggestions gentlemen.
Since the temps. don't appear extra ordinary at this point I am more curious to know why I could not operate the oil cooler fan by jumping the relay contacts than any thing else?

Did it run when you unplugged the fan???

Jordan,
the switch is really easy, you just cyt the green/black wire under the dashboard an put the switch between.
During yesterdays track event, I was very pleased with it! (didn't help me from 'cooking' my brakes & totally worn my tyres, but kept the engine running nice!)
But like Randall & E.J. said, test it first (ask someone with smaller hands to to it
