AC Blower Not...Blowing

Maintenance/Repairs

Hi,
I’ve got a 2003 Mazda 6i with the manual air conditioner (if it matters). About a month ago, the blower stopped blowing. The AC is still working (if I’m going fast with it on, cold air still comes out of the vents, though very slowly), but no matter what I have the control speed set to the blower doesn’t blow at all.

Well, sort of. A few times (maybe four out of several dozen car trips) it does come on, seemingly randomly, after I’m driving for a while (I mean a while - 30-60 minutes later). Once it comes on it seems to stay on. If I turn the car off and back on again, it’s still on. If I walk away for awhile (I assume, if I cool it down) it is dead again.

So…I’m sort of suspecting a bad ground wire somewhere, rather than a bad blower motor or a bad speed resistor (which I’ve replaced once already about a year ago). But I’ve pushed, pulled and wiggled on all the wires I can find under the dash that are related to the AC controls and the blower. No effect.
Anyone have any idea?

Also, if I can’t figure this out, who should I take this to? An AC guy? An electrical guy? The (shudder) dealer? I’m at a loss. For weight. I live in Texas and it’s (still) hot out.

Thanks!
Peter
