Hay all! My blower motor in Mazda doesn't work, so I start hunting down what could be. Found some different threats about Blower motor resistor and so on, but still couldn't fix the problem. I took out Blower motor, connect to 12 V and works fine. I took out blower motor resistor and have no idea if it's good or not (check pictures). I clean it a bit, but still quite rusty. I tried with instrument and it has ~0.5Ω on some pins. I thought that green stuff could be some kind of corrosion but guy at wreck shop said that is isolation? So I took instrument and start checking if there is any 12 V on connector, but nothing get's there. So when I change my switch level from 0 - 1 - 2 - 3 - 4 nothing happens and there is no 12V on any of connectors (I checked on Blower motor and resistor). But when I change to position 1 and 2, ECO light goes ON and radiator fan start working, on position 3 and 4 light go OFF and radiator fan stop working. I don't know how those things are connected? Otherwise my radiator fan work after my temperature goes above 90 (or whenever thermostat open it). So my questions are: 1. Is that Blower motor resistor looks good or should I change it? Where could I find one? Been to local wreck shops and they have same as my (old rusty), but couldn't found new one. 2. How can I test existing Blower motor resistor if it works? 3. Where should I get 12 V before goes to resistor? I saw on Mazda forum that on position 4 (full speed) that should bypass resistor and motor should work. 4. Any other solution how to get it work? No I won't change car p.s. It's Mazda Capella (626) Cargo, 1989, 2.0 diesel
