The fan on my '97 VVC does not want to turn on. When I first got the car a year ago it would come on during normal driving and would run on after the engine had stopped. Then on the motorway one day it started overheating and I couldn't hear the fan so I replaced the CTS. After that it seemed to work perfectly.
In february the Head Gasket failed and I replaced the thermostat, gaskets etc and started it up and waited for the fan to come on, but it didn't until I disconnected the CTS.
Today I was stuck in traffic for about an hour and noticed the gauge climbing (did it a few weeks ago as well) so I pulled over and with the engine still running checked everything and noticed the fan wasn't running. But I have heard it running last week, and it came on when I disconnected the CTS.
Is this a problem with the CTS or is there a relay somewhere that needs checking? I would have thought if the sensor had failed again it just wouldn't work or would be on all the time, not intermittantly working.
