When the AC is working it blows ice cold, but when the AC light starts blinking it blows warm. I took my 4Runner to Toyota. They did a diagnostic of the whole system. They said it had to be the AC switch, but unfortunately Toyota no longer makes that replacement. I found the whole front panel with all three round controls on Ebay. It worked fine for a few weeks. Last night the AC light started blinking again and not blowing cold. I'm wondering if it might be the Mode Damper Servo Sub-assy or the Damper Servo Sub-assy. Has anyone else experienced this problem?
