2001 pontiac sunfire rad cooling fan won't work. Fan, relay, fuse, coolant temp sensor & wiring fine. What's left? When you pull temp sensor connector off, fan kicks in after a few seconds. This model doesn't have AC. ??? Roland

With the fan coming on by unhooking the coolant temp sensor tells me the fan the relay and wiring are good.How do we know the coolant temp sensor is good?Did you test it?Or replace it?Also do you have a scan tool that can read live coolant temp the computer is reading?

Which engine do you have?A scan tool that reads live data would really help see whats going on and help diagnose the problem.There pretty cheap on amazon
