Question on a burban
 

ok, did suburbans 67-72

come with just rear A/C?
or
did it come with Both?
or
Was rear optional?

I seen a Add for a 72 for sell, It mentions Rear Ac, PS, PB, Power Windows and door locks, and rear AC
but not front AC

Just curious on info

Suburbans came with 2 types of A/C. The nicest sytem had the normal dash A/C vents and another A/C blower unit at the back. The other terrible, worthless, noisy, miserable type A/C had only the rear unit with a tunnel that went all the way to the front seat. It shakes and rattles everywhere you go because 30 year old plastic is usally broken by now.

I believe the tunnel type was used up till '71, and the front and rear was used in '72

sub4rvr is correct the funnel style was used from 67-71, and rear A/C with standard dash A/C in front was used in 1972.
We have a 71 with the tunnel style and ours performs Excellent with no noise and will literally freeze you out. I always prefer the tunnel style for the best A/C performance.

So a 67-71 A/C burb will not look like an A/C pickup on the firewall?

Thats right,it looks like a non a/c truck.

burb air
 

I have a factory 71 big block burb that has both factory dash and ceiling tunnel air.

That would be the set-up.I like the air blowing on me like my 72 does.My 71 blows down on you.Is it a late 71?

I just put my rear air unit out of my 72 on ebay a few minutes ago if anyone is interested. http://cgi.ebay.com/ebaymotors/ws/eB...tem=2442894404
