After turning the ignition on even with the center knob in the zero position After about 30 seconds and a bit of clicking behind the center console the blower heater starts and won,t go off.My model is a 20v na with climate control. I ve taken the console out disconnected all the connectors even the one behind the center fan speed knob and it still stays on!!! The one thing ive noticed is the little fan doesn t spin (is it supposed to as soon as you turn the ignition on). I changed the resistor but no difference. Anyone got any ideas please
Sometimes the ECU that controls the heating/ventilation can "go bad" and malfunction, trying another known good ECU from another Coupe can help identify it that's the problem. When you said you "changed the resistor" what do you mean? The large resistor that sits underneath the glove box next to the blower fan? Was it a correct new part, tested used part, or what? The little fan can fail, again try a known good one if you can get hold of one.

It's a long shot, but when the fan next comes on try stuffing your hand up the back of the radio (careful not to cut yourself on the sharp edges of the frame) and wiggling the main wiring loom a bit - sometimes the sheathing frays and exposes bare wires....
