I have a 2000 Mazda Protege, automatic. I've been having a problem with my gear shift; at least, I think that's what the problem is. Whenever it's fairly cool (less than 60 degrees) and dark outside, my car won't shift out of park. It's as if it doesn't realize that I have my foot on the brake. Sometimes if I stomp on the brake, that will work, but not always. Right now, the sun comes up over my apartment building and hits my car between 8 and 8:30 am (depending on my parking spot). Literally minutes later, my car will work fine. Any suggestions on what the problem might be? Thanks!
