Gurgling in heater core. 90 Camry V6. This happens when I turn the heat on after any period of non-use (I live in SoCal - sorry folks). It sounds right under the center dash. Any cause for concern? I replaced the coolant last spring.
ALSO: can the brushes in the vent fan be replaced? I am getting a noisy fan, and the radio sounds static when I turn the fan on.
