I am currently in the process of restoring my Delorean, and one of the many items that is on the "not working" list is the cooling system. I bought a relay update kit a while back so the fan fail module has been replaced with jumpers. The cooling fans would still not turn on, so I jumped the wires on the otterstat and, sure enough, the fans roared to life. Fast forward a few weeks and I have purchased an otterstat and replaced it. The fans still will not turn on when the car is at the correct temperature. My first thought is that maybe the otterstat I bought was bad, but I would like to think that's unlikely as I was careful to not drop it or damage it in any way. Is there any other possible reason for the fans to not work in this situation? I don't know if it is important, but the A/C system is only partially functioning, and the compressor is not currently hooked up.
