Here's one that none of my friends or I could figure out. My 97 Jimmy has
just started to have problems with the blower for the heating system.
On AC and normal cool setting the blower works fine. When I turn the
temperature gauge to hot, both the volume and pressure of the air being
blown drops. This is with the vent or floor settings. Any ideas how to
remedy this or what has caused this?
The vehicle recently had the cooling system flushed, a new head gasket
replaced, and a new thermostat installed. Could any of this work resulted
in this recent problem? Thanks!
