I have 1998 tarus se that the fan only comes on when it is cold outside. When it is 20 degrees it comes on and runs fine .When you shut car off will not come on until car sits overnight. What up with this

you need a transmission fluid and filter changed.because if filter stopped up.transmission fluid little thicker in cold climate make it hard circulate through filter.when engine and fluid get warmer fluid get thinner where it can circulate through filter cause transmission to shift correctly.
Sure the engine coolant will be warmer than the outside temperture and if the car has been sitting a long time in cold weather and the outside temperture warms up it could be the other way around. The coolant temperture sensers aren't real accurate as they are a relaitive senser beween hot and cold and the numbers reported don't have to be real just the change from hot to cold and the reching of the coolant to the operating temperture. Noe it the senser doesn't read the opertating temperture coprrectly you'll have all kinds of problems. The therostaste will try to set the temperture of the water to it's set temperture and can open or close completly to get 195 degrees F. Many times if it's too cold then the stat is bad and needs to be replaced This shows up in alot of cars first thing after winter and the first onset of cold weather when the daily tempertures vary the most from day to night.
Hi. Try to check first your refrigerant. One cause of this problem is refrigerant is running low. Did this happened from the time you turn on the AC? or at first AC is cold then after driving for a certain period of time the AC will get warm?
If the outside temp.sensor is reading -38 degrees then this is what is causing the compressor not to come on.You need to check the wiring to the outside temp.sensor and the sensor.Make sure it is connected.It is located on the front grill area.Between the grill and the bumper cover.Hope this helps.Good luck.
I would check for a bad coolant temperature sensor, of a bad ambient air temp. sensor. You can check these with a good voltmeter, but a scanner would make things much easier. With the scanner, you can se what the computer thinks these sensors are telling it. If it's 20 outside and one of the sensors reads something like -10, there's the problem, but a five degree variation is not enough to make a difference.
Check the B+ cable. If you remove the fuse box cover in the engine compartment (on the drivers side), and you'll see a post with a nut on it, securing a group of red wires. The connector should be a clean copper color. If you take it to a shop, have them perform a voltage drop test on the cable. If it is corroded or burnt, replace that cable!
