Possible fan problem...suggestions?
It’s starting to get colder now in the morning so lately I’ve been starting my car about 10 minutes before I leave for work. I would usually start the car and turn on the heat right away and let it warm up during this time. I’ve noticed lately that the blower set on 1 and 2 seems weaker than in the past. I also notice in the past, whenever I turn on the heat, my fan (secondary?) would kick in right away. Lately it appears that this fan no longer comes on even if I turn the blower to the max (4).
So right now I suspect I have a problem with my fan(s). What is the best way to diagnose my fan problem? Is there a fuse that can be replaced besides checking for any obvious connection problems? Thanks.

I guess I can turn on the AC to see if the secondary fan comes on or not.

Keep in mind that the AC is on regardless of temp selected if in defrost. This (AC or defrost) will bump up the idle. If neither is on, and just the vents on, the secondary fan will not kick on until the engine is hot enough to warrant the extra cooling (summers here in Louisiana will do it while idling).

Thanks for the clarification guys. I guess I was hearing the secondary fan come on much sooner during the hotter days so now that it's getting colder here and I wasn't hearing it, I thought something was wrong.
Maybe it's a seperate issue but I still feel like my fan is weak. Could there be possible leak somewhere in the vent system? If so, how wheree can I check this out?
Thanks.
