My ac only blows upwards thru my defroster
There's a vacuum hose that goes from the intake manifold, through the firewall, to the control panel on the dash board. It's disconnected. When the system loses vacuum it defaults to defrost for safety reasons. HTH. -Jim
Hoses were checked. .even switched out the setting selector thing in the dash. ..will check again tho
There are several doors and vacuum actuators behind the dash. For air to come out of the dash vents you need vacuum at the "mode door" actuator and vacuum at the "defrost door" actuator. This keeps the defrost door closed and, at the same time, directs air to the dash vents instead of the floor (heater) vent. HTH. -Jim
K thanks! I'll look into that
You're welcome. Glad to help. -Jim
would this cause the engine any other type of issue?
My ac blows from the bottom vent and top vent but not to the ac vent to the driver or passanger
