I have a 95 XLT that does not have the climate control.  I have read
about the problems with that unit and the inablility to control the
tempature of the heat, but I'm having a different problem.

So far this seems to happen after everything has warmed up.  I can
turn the heat or defroster on and hear the blower going like crazy
(can even tell the AC is on when defrost is on).  The problem is that
I can't really feel the air coming out any where and moving the switch
doesn't seem to have an effect.  The glove box is nice and toasty, but
the problem is that I only get a trickle of air for the defroster.

any ideas?
