Could use some help with my heat/ac system. The other day, I noticed that when the temp sliders were on heat, the air was only slightly warm, but when a/c on cold, temp was cold. I thought about the actuators, so I looked at alldata info. I see mention of the right and left actuator, but there is apparently a third one... where is that one at? I know it's in the electrics somewhere, though, as for my firs troubleshooting step was to pull the fuse for the actuators/hvac for a minute (listed calibration procedure) after putting the fuse back, heat was restored, and the pass/drivers side actuators switched from heat to cold. next day the heat came and went intermittently....
i cant make out from the alldata info where the 3rd door is (which i gather controls heat/cold entering the ac system upstream of the pass/driver actuator?
