[QUOTE="BlackRose#1, post: 26802, member: 14531"] I have an issues with the firewall insulation rubber drying out and breaking off and actually crumbling and interfering with the actuator motors, creating a whining and crunching sound resulting in the system going to. Default on constant defrost. Be aware, if you go to O'Reilly's for a MODE actuator, they will sell you a blend door. I learned this by calling doman directly .if it's a plastic gear, it's not a mode, but a blend door. [/QUOTE]
