Having problems with your 1988 GMC Suburban ?
Where does the vacuum line to the heater control valve come from
\015 I completely removed the rear heater assembly. The valve that is on the fender well is bad. Do I need this valve or is it something that split the heat between the front and the rear or is it what controls cab temp? Is there something that a regular pickup truck uses to control cab temp?\015
Answers :
I think the line your speaking of and the valve would be cab recycle or fresh air intake.
