Hi there, I am Cam. So the engine fan comes on at times when it should not, am I understanding that correctly?
OK, Which fan, the fan inside the vehicle or the engine fan? And the lights, that happens when you add the load of the power windows?
Ok, Does the dash show the check engine light as well?
Ok so its likely that your fan clutch has failed or the relay that controls the fan has failed. There is a device much like a relay and that looks similar to a relay for the engine fan in the under hood fuse. This is common for failing. There is another one for the Low beam headlights. Swap these to see if the fan acts normally or if the low beams go out. If so then the relay is bad. . The numbers on the top are 15016745. That is also the part number to order if that if the lights come on.If that does not correct, then you likely have a bad fan clutch. This electrical load could be made worse by using the windows and such resulting in your other issue.
You are most welcome.
Ok but did you swap the 2 relays to see if the issue remained the same?
Ok if you removed the fan relay and it stayed running then it confirms your fan clutch has failed.And sorry for the delay, I am also a paramedic and I got busy.
