Tried disconnecting and shorting the switch during the electrical gremlin chase. It did not make any difference. The signal comes from the a/c controls and then through the relays. The system is currently under vacuum awaiting freon. The thing is that I have never heard the radiator fans run. The temp has never climbed up past 90. I have only had the car for a week.
I am not sure if this is normal or part of the problem. The high speed setting on the interior fans runs on slow with just the key on and then runs the normal fast speed when the engine is running. There should be no difference in fan speed between the key just being on and engine running. It seems like a back feed or bad ground.

I think this problem has been there for some time. The person I got the car from picked it up with a broken timing belt. He never had the car working till the engine was done. I asked if he disconnected the compressor or set it to the side and he claimed it was set aside and the system left intact. On my other 4 Lotus I can find all the parts of the wiring harness. This car is taking longer to learn about.
