Car won't turn over had the battery replaced but still having problems usually in cold weather but not all the time?

You need to check and/or replace the thermostat and/or the temp. sensor. Take a meat thermometer and stick it in the overflow tank. The temp gauge on the dash should register above the 1/4 mark after at least 15 minutes of driving. If so, the meat thermometer should read above 180 degrees. If the meat thermometer reads 180 but the gauge isn't above 1/4, then you need to replace the sensor. If the meat thermometer doesn't read 180 or higher, then you need to replace the thermostat. The thermostat in these cars, though it doesn't fail on its own, has an unnecessary rubber gasket that fails, and allows coolant to leak past even when shut, causing the engine to not warm up thoroughly. IF the engine doesn't warm up, the idle won't come down--speaking from personal experience. I had to replace both items on my car. Now it idles fine, and after a bit of driving the gauge registers between 1/4 and 1/2, but always above 1/4. DO NOT tamper with idle adjustments unless you have exhausted all other possibilities. They are factory set, critical, and almost never need readjusting. Good luck.

its the passlock system. The passlock wire is tiny and fragile, and gets disrupted causing your car to think you are trying to steal it everytime you put your key in.

now you can search for this video on youtube, this is where i learned and ever since i did this i have had NO problem with my car starting for the past 5 months.

you need wire nuts, wire cutters, electrical tape, n socket wrench to take apart steering column

first, go to your fuses, find the airbag fuse and remove it just incase you snip the wrong wire. what you do is look below your steering wheel and take your steering column apart. there are a serious of wires electrical taped together that are plugged in. you peel all the electrical tape back exposing the wires, and you find the WHITE wire. its all white, no other color. This wire is for your Passlock system.... this is the wire that got faulty and is causing the car not to start. now what you do from here is kinda tricky, not too bad though.

Seclude the white wire from the rest, so that you are ready to make your cut. Now, what you do is start your car, leave it running, and while its running you cut the white wire in half. then after cutting the wire, turn your car off, and then turn it back on. it should start right up. Then just put wire nuts on the two ends, and electrical tape them back together

The point of doing this is, one is disables the passlock system completely, and two the reason why you do this while the car is running is because snipping the wire with the car running makes the car think that it got into an accident or something, and puts the BCM/car into a "Fail-safe" mode, making it start every single time no matter what.

i thought this sounded insane at first, but after searching for a couple of hours its the only answer that made sense. and now i am the happiest camper in the world as far as it starting

Hi there, Best thing to do is buy a Haynes or Clinton's repair shop manual at your local AP store for your particular vehicle. Then read up on it in the trouble shooting section or the step by step RR section. You can purchase these at your local Auto Parts store or buy them on line at ebay burdfrenzy

Apparently a lot of people are having the same problem, including myself. What I've read is it's a faulty ignition switch that has to be changed at a dealership, because it also needs the computer to be reprogramed. Big bunch of hookie to me, but my car started doing it about 2 months ago and now it's not even turning over at all.

sounds like the cold cranking amps ( CCA ) ARE TO LOW FOR YOUR ENGINE. COLD WEATHER HAS A BIG EFFECT ON CAR STARTING, WHEN ITS WARM OUTSIDE THE ENGINE DOES NOT NEED AS MANY AMPS TO TURN OVER. go to any auto parts store and they will tell you the correct size battery for your car. I know, it gets pretty cool here in nys in winter. have a good day !! I have a malibu 3.1 and i have a 875 cca battery in it.
