OK, I'm talking about a st162 and it has 2 fans, one for air con and one for radiator. the air con one works fine but the radiator one doesn't start. The fan itself should be OK as it run full-time if I plug the switch cable off. I suspect the fan switch is dead so I changed it with another one from a wrecked car but still not working.
The question is.. Is it the fan switch problem(luck me getting both car's switch dead)? or can it be somethine else? How do I test if the switch is dead? Hope I'm making more sence now..
V8_MA61: Thanks for the help, I'll try it tonight.
