Climate Controls...

#1

Post by ssava » 30 Nov 2019, 11:07

Hi all!
Any chance someone has a diagram of the vacuum system hook ups to the climate controls for the 67 XR7?
Our blue shop manual book doesn't seem to have the info we need.

Still working the bugs out to get the defroster to work.

This also shows the early in the model year vac canister (before Dec 66 built I believe) but that's would be the only difference. Your vac can may be outside the fender apron in the wheel well rather than under the hood hinge on the inside.

Thanks.
I'm actually talking about these vacuum hoses that go to the various parts of the heater core and such.

The bottom one gives the hose color codes at the control panel vacuum switch. Those are exactly what you asked for. There is no better information.

I strongly suggest you replace all the vac hoses. They tend to crack after 50 years. I tried years ago to reuse the old hoses on a customer cat. All we got was continuing vac leaks... Kits are less that $20, or buy bulk. Of note here, the controller tends to go bad too & have vac leaks & intermittent control. Classic Auto air offers a replacement.

Thanks. We did.
Turns out the actuator was broken or leaking vacuum. So that's why it wasn't working. We traced/replaced the vacuum hoses from manifold throughout and it all came down to that one little guy in the dash.

Since she's my daily driver and I need the defroster in the winter, my son unscrewed the control arm to get it to default to the right position and it works fine for now.

Eventually, we'll want to replace the unit when we can take apart the dash and get in there properly.

Thanks all for the help!
