A/C question

[medicman775]

Did burbs come with rear a/c only? My option sheet says air cond overhead system and I have the ac lines to the rear ceiling but my dash doesn't have the a/c vents and my controls don't have anything labeled for a/c control. I assume my dash is the original.

1972 was the first year for an in the dash factory type A/C setup on the suburbans and was refered to as Front & Rear A/C which also included the rear section only headliner mounted a/c pod. If talking just factory a/c and not dealer installed, the 71 and prior burbs only had a headliner-roof mounted a/c setup that ran from the front to the back and had no a/c controler or a/c vent option in the forward dash.

The rear only work great too! The one I found is actually two twin units together.

Thank you for the info. I only have the hoses in mine. Are any of the other parts available?

The rear A/C unit from a 73-91 burb, including the housing can be fitted into a 67-72 and look like it was made for it. Very minor bracket fabrication is required....
For dash air, I prefer an aftermarket heat/cool/defrost unit because they mount completely inside the firewall.
I'm not certain that even 72 dash climate control used the a/c as an air dryer for the defrost, blending a/c into the hot defrost air being blown on the windshield. I'm not sure when this de-fogging feature was started, but all the aftermarket heat/ac/defrost units incorporate this feature.
