Sunload Sensors

[1999Silverado]

I'm still doing a little more digging into the 'manual to auto' HVAC changeover and have a request for one of you guys. Would someone that has an 05 or 06 Silverado with the AUTO HVAC system verify that there is more than a SINGLE sunload / ambient light sensor in the middle of your dash please? According to the diagrams and drawings, there is suppose to be 2 additional sunload sensors (1 for the driver's side and one for the passenger's side) - but I havent been able to get a view of an 05 or 06 dash to verify the locations. If they are visible, would someone post a picture for me? Thanks.

It looks like there is two different ones from the diagram but the connector end view shows both circuits in the same connector.

 

Edit: yea looking at the diagram again there are two sensors but they are in one assembly.

As stated above, the auto climate dash looks exactly like the manual one, no physical difference

Would that be the sunload sensor in the middle of the dash? The one I picked up for the auto HVAC is P/N 25713063. 4 Pin Connection, looks like there are 3 sensors on the inside of it - one is definitely a photo sensor but I'm not familiar with the other two.

 

BTW, thanks for the info.

yeah, it is those three sensors crammed in the same part, as you observed: More connections.
