HPI Vorza 2/17/2011Blend door actuator problem. Its a small rectangualr box located under your dash towards the center of your vehicle. Its a door that swings to let cold or hot air in, if this gets stuck or doesnt open then thats when the problem starts. Its a pain in the $#% for me since more often than not it requires removal of the dash area.
Unfortunately, i was unable to find a guide specific for your vehicle but i found something which will give you an idea on how to go about it.
