alright so i have a rex with a d16y7 in it. ive had it for almost a year and i drive it everyday and the fan never came on. The temperature stays alittle less than halfway and it never overheated or anything. so yesterday i drove like 20 miles home and the temp was normal and i left it idle in my driveway for 5 minutes cuz i was leaving again. the temp was normal but the car just shut off. then when i turned the key everytime the fan would kick on and the car wouldnt start. i unplugged the fan and it started and ran fine. plugged it back in and it stayed off and ran fine. what the hell is going on?

 

no one has any guesses?
