It is a single temp system. The air from the driverside vent is the same temp as the passenger side vent. the air seems to come from under the dash. not out of the vent. do you think it is still the actuator?
I have the same problem with my 2000 Tahoe. IF you find out what it is I would love to know. I replaced the filter and even tapped shut the recycle vent. Mine is like there is a whole in the dash letting in cold air.
I have a 2000 chev Tahoe. On cold days I have cold air comming in on the passenger side of the dash. I still have heat coming out of the vents. I changed the air filter and even plugged the recycle vent and I still have a lot of cold air comming in.
Any idea's
