Part II - purchasing the A/C controller / switch

[Springthing]

Ok, so I need to buy the A/C controller to replace the front/main one.

In looking around for the controller/switch I've finally got to looking around and noticing that there is no button for the rear defrost. I have the lines in the back window but no button to speak of to turn them on!

Question is.. does anyone know if I can buy the controller with the defrost and upgrade the 'Burban to now have a rear window defrost by (hopefully) plugging an extra plug in back of the unit that's currently probably not attached to anything?



Again, thanks in advance!

I am not sure why your burban doesnt have the button if it has the rear defrost, my guess someone replaced it already and just didnt care to get the right one, I have never seen a suburban that never had rear defrost so most likely that could be why the controls dont work right is that it isnt the correct controller, but yes you can find the right one easily. It shouldnt be that a wire is just hanging someware, I am assuming its just a harness that plugs into the back of the HVAC controller and there is simply just not a pin for the current HVAC controller. I can get a close up my HVAC if you would like so you can get the proper one, mine is also a 99 burban
