2006 chevy suburban ac/heater
my front ac/heater does not blow unless going at
high speeds for long distances. The back blows
cold and hot still. I have changed the blower motor,
blower motor resistor, blend door actuator, the
relays under the hood and the fuses. I thought it
was the actuator because the old one makes a
buzzing noise when plugged in new one doesn't.
Any one know what the problem might be we are
hitting 109 degree weather i really need my ac
