Hello, I had to have an unusual experience a few days ago. And that was the temperature of my 3.0 V6 shot up into the red area – and that at -12°C outside temperature. Of course, I’m interested in how it came to this. First I suspected the fan motors along with fuses, because they didn’t start when the climate was switched on, which is usually the case… Furthermore, I found that the terminal 4 in the central fuse box (according to the manual there must be a 15 Ampère fuse) is not occupied – no contacts in it, which could take a fuse – very mysterious…. Since I did not know any further and the car had cooked, I had to leave it standing….. The next day I had to make a ride (outside temperature -1°C) and tried to put the climate back into operation – and look, both fan motors were running – impeccable. But it is inexplicable to me why the fan motors mi t climate sometimes work and sometimes not; and without climate not at all?!?? My suspicion now applies primarily to the thermoswitch (if the omega has something like that). In my Corsa A it was once broken and then the fan motor didn’t jump on either….. How can I check/replace/bridge it if that’s what it is? Or is it electronically otherwise regulated by the omega? And where is the cooling water thermostat (suspecting moment Numero 2) and is this perhaps electronic I know that’s a lot of questions, but maybe someone can help me… Thank you so much, Vince.
