On my 92 SL DOHC the average temp on the C to H dial is about half way; summers it moves a little over the half mark, winters it stays under.
But when I get stuck in stop 'n go, it climbs up and touches the red zone. Then I do what everyone else does, I punch the a/c button, then punch it again to get the fan going. I don't keep the a/c on because the temp runs back up. The fan cools the temp down quickly to a reasonable amount above normal. If there's 40 minutes of this kind of traffic, that's a lot of punching on the a/c button.
It's too much to expect there is some way to get the fan to work like they do in normal cars; turns on when the engine starts and turns off a few minutes after the engines stops regardless if the key is in the ignition or not. But is there some way to rig the fan relay or something else to get the fan to start when the key is in the accessory position ? Or has anyone figured out a better solution ?
