My borther just picked up another e30 a few weeks ago and having a problem with the electric fan staying on. If we turn the ac on the fan stays running when we shut the car off. The fan stops with the engine off if we remove k1 relay but stays on if we remove k6. We replaced k1 but it still happens. We checked fuse 20 and it has 0 volts with the key off. Do you think He's lucky enough to have two bad relays? Has anyone had a similar problem? If we pull out k1 the fan stops and doesn't start when we put it back in. The fan doesn't start if we jump the switches with the key off. Any ideas would be greatly appreciated. Thank you.
