my fan wont turn on. i turn on my motor left it there and notice my fan is taking a long time to turn on. it work a couple days ago. now dead. i waited and waited outside and look at the fan until i went back in the car and notice my temp gauge was sky high! i turn off the motor. when i turn my heat on full blast, my temp gauge seem to go down, but goes back up when heater is off. my fuse under steering is good, all fuse in engine bay seems to look good. now what?

 

take off the plug on your fan and get a line and directly connect it to the battery to see if the fan turns on...if it doesn't then its your radiator fan thats messed up.

 

Car, year, motor etc?

My guess is your temperature control sensor, the one that plugs basically in right by the t-stat.

 

check all the fuses first then go from there.

That is the most common problem. Coolant temp switch.

 

Check the fuses, both underneath the dashboard and in the engine bay. Then jump the relay in the engine bay box that controls your fan and see if that's the problem. Probably something simple like a fuse or the ECT switch screwed into your engine.

 

your thermostat could have taken a ****.
