My 2005 Toyota Corolla (CE) won't start in cold temps. IT'S NOT THE BATTERY! When the temp warms up it starts. If the headlights are on when the key is turned, they do not dim. I think it is the starter, but expensive to replace as a step in trouble shooting. Of course, the starter checks out fine when we bring it in because it is warmed up. What do I do?

I appreciate the answer. Now let's see, I did say its is NOT the battery. We have regular maintenance on the car and when the problem first appeared several years ago, we had the battery replaced by the dealer and the problem persisted. They said to leave the car with them overnight so they could try it in the morning. We need our car every day and they said about $500 to replace the starter. I am hoping someone has had the same problem so I can be sure if I spend the money to replace the starter it will fix the problem. But it is definitely NOT the battery, it's pretty new, dealer installed, and tested. I appreciate the answer. Now let's see, I did say its is NOT the battery.
