I have a 99 Sunfire 2.2L no A/C, Auto and 105,000Km.
The cooling fan is not turning on at all. The fuse, the relay, the coolant temp sensor, and the fan itself have been checked and work perfectly. I have also checked the circuits for the coolant temp sensor and the fan and they to check out okay.
However when I unplug the coolant temp sensor (with the engine running) the cooling fan comes on right away. My guess is the PCM.
Anyone have any other ideas?
have the same problem?
