Hey guys, look i know that lots of people have started topics about this but i have a slight problem... well a big one seeing as there are so many faults. i have a 1990 180sx and it has a digital climate control unit from factory. when i bought this car it never worked, ive looked all over it and nothing seems wrong. all the plugs seem to be clipped in properly etc. ive even checked the blower motor resistor but it all seems to be fine. When i cycle through the diganosics system on the head unit it just comes up with nearly every possible fault code which is screwing with me, am i missing something obvious or what!? Cheers Jack.
