Heater valve delete and Smog delete Question
First of all and most important, I Have Searched!!
I have done both of these to my 92 RS 305 TBI and there is a vacuum hose that runs through the firewall to the air duct actuators behind the dash, I think. Anyways, what do can I do with the vacuum hose that went to the top of the heater control valve?
Also, were there any vacuum hoses that went to the smog pump?
And what can I do with those?
Thanks
Chris.

I was thinking of that, but I done a search on it and found out that some members were experiencing only defrost when the controls were set on heat.
I found a place on the intake that had a vacuum port on it. I will try that and see how it works.
Thanks, Chris.

Defrost is the default setting when no vacuum is available at the controls. So either there was a massive vacuum leak or the wrong vacuum line was removed.
