Re: it's snowing! and CQ heater help

Tom;

    The chirp is coming from the blower motor - likely dry  or worn fan end
bearing. I had a '86 5ktq which used to chirp on hard left turns and on
large bumps. I solved my problem by drilling an access hole in the blower
housing and running WD-40 down a wire onto the bearing. You should plan on
replacing the blower motor - if it is original, the brushes are likely worn
out. You can check the brush wear by looking at the position of the shunt in
the brush holder slot. If it is near the bottom of the slot, the brushes are
done. The shunt will eventually hang up on the bottom of the slot and lift
the brush off the commutator - voila, no more chirp, but no more heat either
:o)
