Yesterday, while sitting in traffic in my '95LS, i noticed my temp starting to rise a bit from dead center as it's always been for years. I immediately got out of traffic, and as soon as I started to drive, it came back down to dead center. A couple of more times during the day when stopped at a light, it would start to creap up, but again...once I got moving it would come back down. It's never done this before.
I went back out several more times during the day, as well as this morning, and it hasn't done it again, regardless of how long i sit still. Very odd.
Anyway...does anybody have any ideas of what could have caused this? Also, while I had my hood open, i did notice that the small fan that is in front of the radiator is not on. I stood there with the car running and the AC on, and during the 5 minutes I stood there, it never came on. However, the temp never rose either.
Any insight here as to things to check before taking it in? Fuse somewhere for the fan? If so, where?
Thanks in advance!
