Going into the belly of the beast

My blower fan stopped, but before I rip into that area to replace it, I wanted to ask, is there anything else I should check first? I've checked the fuse, and the regulator was replaced 3 years ago. I would hate to rip into it, replace the fan, and find out it still doesn't work because something else was causing it.

Also, there's obviously a secondary fan, because I can still run my defroster, and it blows some hot air out, not a lot, but some.

Thanks,

I would trace the voltage along your electrical lines. Do you get voltage at the plug which connects to the blower? If not, do you get voltage at the part before that? That's how I troubleshooted my non-working blower-- traced the voltage. After replacing a mechanically dead switch, I confirmed voltage to the plug that goes into my blower. Replaced the blower and all was good.

I'll check

I'll try to check that wire, from where it comes from. I am trying to avoid digging out all the stuff to get to the fan, and testing it there.

Thanks.
