Thanks everybody
who replied. I have been so swamped that I haven’t had time to write back. I do
think it's steam from the heater core. It was a chilly, rainy night when I noticed
it. I had used the defroster a week earlier and was surprised at how it didn't
seem to clear the windshield very well. It probably was throwing more moisture
onto it. that night was not cold or rainy but the windshield had condensation
on it from sitting all day with the windows closed. I will try it again on a
less damp occasion and see if it still appears to be "smoke". I don’t
think it was electrical because there was no smell of plastic and also because
there is no electrical connection involved in opening or closing the heat flapper
door. Also, the "smoke" was coming out of the vents. Does
anybody know the procedure off-hand for changing the heater core? Should I also
replace the blower motor while I'm at it? Right now I don't even know if the motor
is just not hooked up or if it's totally dead. There are 2 wires on my front
harness that I never did figure out what they are for. Thanks, John Nasta -----Original

should have the heater core checked. The situation sounds familiar. When me and
my brother were leaving school in the 1990 Caprice that my parents used to own
he put on the heat. It was the middle of winter. He noticed stuff, almost like
snow, coming out of the vents. It left a film on the window. Turned out that
the heater core was cracked. Think you might want to have it looked at. |
