Hi,
I know this is a well traveled road, in fact there is so much info, sometimes its difficult to pick out what you need.
After spending $1000s I have beatiful ice-cold AC in my 86 C20 Burb. However, all that air is going straight to the floor. When selecting the different modes on the dash control the AC compressor will switch on/off correctly according to the position, but the rod that actuates the big door behind the glovebox doesnt move.
I can move it freely by hand, and the door(s) open and close correctly without interfering with each other.
Is that rod assembly actuated by vacuum, or is it cable operated (and therefore im missing a cable...) All my vacuum lines appear to be connected, but I cant 100% say its all correct as someone has been messing around in the last 40years and who knows what they did.
Anyone who has been through this before, would love some advice on how to get the mode select working again.
